2) Even the people who like you said don't know any better and don't have any problem going on their ways, I mean to me that is just a diluted version of homophobia, because what are those people really saying? "Okay you're gay/bi/ace/trans that's none of my business and I just can't support you" which honestly doesn't sound all that bad except for the fact that it still means that they think homosexuality is wrong and unnatural.
And I can agree with that I suppose, the diluted version of homophobia. But the meaning changes so I suppose that’s why. It’s definitely watered down.
I will say that I do like that the world is becoming more open minded and accepting about these things and while I believe that there will always be those people who think that it is wrong, there will be a day when this is a rarity.
