When someone thinks homosexuals shouldn't exist... How can it not be hate?

It's more ignorance than hate. But it can also be hate.

exactly...it's ignorance and hate

Very true it’s 100% hate..

It's either hating the people themselves or hating that people are having these feelings, I think. In that sense you could always say there's hate involved. :?

Hating just because you don't like it is ignorance.
But as you get older no one will care what you are. You will be lucky to get any attention at all.

Homosexuality is a choice.

i have beat up a lot of straights that tried to beat me up for my being gay.

Because it's just funny. Other people's brain-wrongs aren't really hate. It's just a lifestyle choice...

People are allowed to express an opinion - free speech unless you disagree with that person

They're usually not saying the people themselves shouldn't exist. But the fact is it's none of their business.

I don’t care if people disagree with it but to shame anyone for safe consensual things between adults is stupid.
