people will use the worst moment of your life to discredit every good thing you’ve ever shown them. apparently your kindness is fake but your anger is the real you.
It's okay to disagree with a person's lifestyle if they're gay. But otherwise making them a public spectacle is actually wrong. And it's immature.
But if this person seems to try to force themselves and their beliefs on others, that is a problem.
But if not, leave them alone.
