There is so much that is so wrong in these comments, but I have only one thing to say, to Ben Levi: I am a liberal, and a Jew, and I know way more American history than you know.
Speaking of history, I remember when conservatives favored the prosecution of burners of the American flag, and a case went to the Supreme Court, and the court upheld the burning as an exercise of free speech. I remember when conservatives wanted to prosecute leftist wearers of shirts that looked like they were made out of American flags. I cannot remember whether there was a prosecution or Supreme Court case on the issue, but now you can buy such shirts on line, and conservatives wear them at conservative protests.
So if you feel like burning a swastika flag, you have liberals to thank for bringing a case to the Supreme Court and affirming that right.
