What defensive tactics do you speak of? Would you have us just line up on the Mexican and Canadian borders and take turns making sure no one comes across? I love you libertarians use of the "defense instead of offense" mantra but you never explain it. You can't put your head in the sand and hope no one comes over here. It doesn't work that way. One of the first things the founders did, upon declaring independence, is send John Adam and Ben Franklin to France. What would you have had the founders do if the Brits would have assassinated them? That's no threat to our soil is it? We just let those two great men be killed with no reprecussion?
As far as the US Government taking your freedoms, sorry bro, I don't speak for the legislators that take our freedoms. If you have a beef with them, I suggest you write your congressman instead of trying to find a way of making me responsible for it. There's also that whole moving to another country thing. I mean, if its that bad, just leave. Its hard to get into our country legally. Not out.
