It's not the judging that's problematic but the result of that judgement.
People can think being gay or lesbian isn't normal all they want. They have a point. If it was normal than our bodies would be made for it to be normal and they aren't. That's the most obvious thing that says same ### couples are wrong.
But why the hell would someone advertise that thought? Calling people beasts, saying they're disgusting, etc. is not how you deal with it. You're suppose to tolerate it. Live with it. It's not going anywhere so it's no point in trying to change that.
