Shame on the LIV in the crowd booing this brave man for exercising his First Amendment rights...
That’s part of their right, too. The 1st Amendment doesn’t protect you from ridicule. You have the right to free speech, but nobody’s forced to listen.
Why? Those booing were exercising their “1st amendment right.” I don’t agree with them, but they have the right (and it doesn’t come from the 1st amendment - so your comment is doubly wrong).
