Since when did everyone start hating LGBT people?

I remember in 2015 when Obama lit the White House up in a rainbow. It was beautiful. It’s been all down hill since then. I have seen so much hatred and disgusting things, especially on Facebook, since then. Why all of a sudden did people start detesting the LGBT community? I came out as a trans man in 2015. No one was talking about us. It was amazing. Now the right wing won’t shut up about us and I’ve even seen people saying we should be executed. Wtf happened to my country?
