Saying gay people shouldn't get married isn't a political opinion, it is you said it first, just hating arbitrarily a randomly assigned group of people.
Are you suggesting it's the same ballpark as saying "I don't like the current elected official?"
And people wonder why politics is so divisive now. It’s not longer about disagreeing with someone, it’s about painting them as immoral and not worth engaging.
Have concerns about immigration levels? You hate immigrants and that’s wrong.
Worried about crime? You hate minorities and that’s wrong.
Worried about government spending on welfare? You hate the poor and that’s wrong.
Everything else is hate and shouldn’t be allowed.
