You're okay with dudes being able to hold daily anti-USA, pro-ISIS meetings, on US soil, then order crates of AR-15s... as long as they don't break any laws.
At what point are they aiding our enemy at time of war?
Interesting how you reach to extremes.
However, if my answer isn't clear enough... I will say again. In this country you can SAY whatever you want... It's when you DO something to others, that we have an issue.
You want to police people's thoughts also? Sounds like that's what you're trying to do. Why are you so interested in big brother telling you what to do?
PS... in 1776, they had meetings that were Anti-British... Those meetings created this country we live in today.
That's what makes this country so great.
