1) Politics has been many things. Quests for power, glory, wealth, control, whatever. Politics is moreso about manipulating people than it is about moving resources from point A to point B. I believe it often has less to do with the distribution of resources as it does with control over the distribution of resources.
2) Taxes are not inherently socialist. Social control and administration of the means of production is socialism, specially the unequal distribution of wealth and compensation according to work done. True, it is widely held opinion, among capitalists and socialists, that socialism == high taxes, entitlement programs, etc. This is not necessarily the case, just common enough that people automatically assume so. I do love the nice false dichotomy you tossed in, very clever I must say and fairly smoothly delivered. One can obey the Constitution and live in the modern world. It is hard to imagine, as we've ignored much of the Constitution for so long, but it is entirely possible.
I must ask, you obviously have great disdain for the Constitution. Would you prefer, in your preferred socialist America, to junk the entire Constitution, or just the parts you happen to dislike?
3) Oddly, we have a member here from Sweden who would love to escape his socialist paradise for our evil capitalist empire of oppression and inequality. Same with MicroBalrog too, oddly. I met many folks from both examples you cited who wished to come to America. I tried to always ask why, and the usual answer was "For a better life". Funny, that.
As for socialism != collapse, socialism has only taken root since 1951 and progressed relatively slowly since. Even communism lasted 70 years. Socialism and communism are not the same thing, on paper. In real world, they're not exactly unrelated. Historically, there has been strong ties and much overlap between the two. To claim that no such link exists would be disingenuous at best.
4) You are entitled to hold whatever opinion you wish. I don't care for the juvenile insults like "libtard", "rethugs", "demorats" or the like. In general, this board tries to discourage it. But folks always come up with terms for folks they don't like. It's not exactly dripping from every post, as you may have noticed. Also, note that not a single person wants you banned. Most posters are relatively eager to engage in a relatively civilized philosophical conversation, with a higher degree of reason and logic than is norm to the internet. Perfection we ain't. We're merely an armed polite society, by and by.
As for group-think, you obviously haven't read any of the 9mm vs 45 or Linux vs Mac vs Windows threads. We have lawyers, German politicians, wacko libertarians, liberals, cops, geeks, grammar nazis, etc. Just because we manage to get along in a relatively polite manner doesn't we all have the same opinion.
5) If you had a "libertarian phase", I'll be suitably impressed. How long did it last? Did you put in plenty of research and thought, or did you give it a passing glance? I'm not being judgemental, I'm obviously not you so I don't know how serious you were about the matter. Not saying you had have a shrine to Rand in your living room or whatnot, but it'd be hard to take your former libertarian "creds" seriously if it was a six month fad.
And gods damn it, they're dark green. NOT black. Green actually has better IR properties. Some of us work with said "black helicopters" and prefer a bit of accuracy.
6) I'm a fan of the Constitution. I encourage and support applying it to every American, regardless of race, gender, creed or any other indicator. I've donated plenty of money to the EFF, which is the most effective civil rights organization in the US. I suppose that's "social reform". I do not consider creating inequality as social reform, which is what socialism is. Socialism by definition is the unequal distribution of wealth and compensation according to work done.
I have encouraged RKBA folks to reach out to folks outside their normal niche. But asking them to sell out their souls and their freedom to socialists would be a waste of time. Socialists by definition wish to restrict freedom (granted, primarily economic freedom), not encourage it.
Remember, our government is SOLELY granted abilities from the Constitution. It specifically states that only matters specifically delineated in the Constitution are allowed to the federal government. Everything else is reserved to the States or the people. One of the major points of the Constitution was to prevent the tyranny of the masses. Civil rights are not entitled to restriction from a 51% vote. The Constitution doesn't GRANT any rights, only specifies some of the rights you are born with by virtue of being a human. I fully realize this has not always been the implementation. It took certain minorities and women many years to get the recognition they were entitled to from the day the Constitution was signed. Those infringements are ENTIRELY due to people like yourself believing that civil rights can be infringed, if you just have enough votes.
Of course, I imagine to most of you I am still a horribly mis-guided, stupid, possibly evil, cretin. So be it, I do not hold you to the same opinion even though we disagree on some politics.
To be fair... We want to take nothing from you. We don't want to take your money, your freedom, your liberties, your lifestyle, your opinions, nothing. You desire to take from others involuntarily to give to those who have not earned it, restrict the economic freedom of others, restrict our lifestyles, etc. I don't know if you'd like to take our civil liberties and opinions, but your contempt of the Constitution which protects said liberties and opinions is suggestive. I'm glad you don't have those opinions towards us... But I'm not sure how you could think that we are misguided, stupid or evil when we wish you no harm nor wish to infringe any of your civil rights, liberties and freedoms.
