Bear in mind, I'm not against "radical" ideas.
But, as has been stated earlier, the more radical the idea the more presentation matters.
If you want to propose a radical shift in policy then the people presenting, and publically supporting, that shift need to be as calm, vanilla, non-threatening and patient in presentation. You're selling something, act like good salesmen, blend with your prospective customer.
If you want to change something in the majority, it is best to actively conform to that majority in every other outward appearance. Anything extraneous you do that is weird or scary gives that majority, whose buy-in you absolutely have to have, a reason to reject (or ridicule not on the merits) your position.
It is not enough to be "right", you have to be right in a smart, downright crafty, manner.
Similarly, you should attempt to change one thing at a time (incrementalism). Don't go pushing for a return to the gold standard, abolishing the Fed and no gun and drug restrictions all at once in every press conference or presentation, even to the faithful.
That is too big of a bite and in seeking to get all, you'll get none. That again needs incrementalism, turning up the water temp one issue at a time so the frog majority can get used to the idea.
That is what the Left and the statists have been doing all this time, little bites eating the elephant.
Meanwhile the radicals of freedom keep trying to shove their platform down America's throat all at once.
