While I agree with you in principal on the 1st amendment I have to wonder if the 9th doesn't supersede it in a situation such as this. The 9th states that your rights are innumerable. They are infinite. Therefore, under the 9th you have the right to take extreme offense to what they are doing and also have the right to beat them for it. Under the 9th they have the right to defend themselves whether it be physically or legally.
In other words, this is a free country, you are free to do whatever you want up to and including murder. Society, however, has the right to demand that you pay consequences for your actions up to and including death.
or, you have the right to take them out but once you exercise that right you have forfeited all your freedom and probably assets for some period of time. The question then becomes, "Is it worth it to you?"
Then I guess you have the right to resist the govs attempts tio incarcerate or extinguish you.
Long live the revolution!! (We really need a smiliy shooting in the air for this one) Disclaimer, this line is tongue in cheek the rest really isn't, on principal anyways.
