It is true that I am not LGBT. It is true however, than many of my close family are. It's also true, that I was highly politically active in Canada twenty years ago for legalizing same-sex marriage. I debated Michael Coren about it on TV. I also volunteered for years at the Pride Remembrance Run in Toronto at the beginning of Pride Week.
It may not be my lived experience personally, but as someone who has previously been politically active in pro-LGBT politics, I have certainly been under attack and experienced the bigotry. You really don't have to convince me.
I totally understand how unfair it is to have to fight for your rights and fight to exist. There's nothing fair about it.
But if you give up on trying to change people's minds, you're just ceding the playing field to the people who are willing to change people's minds against your own interests.
