I can buy an American flag and burn it. I can buy a Pride flag and burn it.
I can't burn my neighbor's flag. I can't burn a flag outside of a business.
THAT is how the First Amendment works.
I complimented a woman on her dress at the store once. She smiled, thanked me. A woman behind her said "Are you objectifying this woman?" Before I could say anything, she looked at her & said "Oh shut the hell up. He's being a polite gentleman." There is hope for sanity.
