Banners? I don’t use banners in themes.
I don’t even know why it still exists tbh. The same reason racism and homophobia and sexism and other forms of hate still exist, I guess. People hold hate in their hearts and they just can’t let it go. They can’t just look at another person and think they’re human and just like them and move on. Everyone needs to find something to pick at.
It’s really good that you found someone who makes you feel happy and comfortable with who you are. That’s one of the best things about having a partner. They look past what you thought were flaws, or they enjoy those flaws as if they aren’t flaws at all, and it makes you feel really good about yourself. Everyone needs another half like that.
