Giving somebody the finger is an ACT, but it says something too.
Personally, I oppose an amendment banning flag burning. I think a law that says anyone assaulting anyone burning a flag cannot be prosecuted for assault would work for me.
If burning a flag is speech, then that "speech" is "Fighting Words", and deserves an appropriate response: A couple of left jabs, two rights to the face, an uppercut to the jaw, and a size 12 to the groin would do it.
How many of these left-wing scumbags have the guts to take a beating for their despicable acts? None. Flag burnings would practically disappear from public discourse.
