Because he appointed Pence who believes in gay conversion therapy. And because his platform contains various mentions of rolling back LGBT rights.

This is a good example of people believing msm propaganda and not thinking themselves.

Trump has been advocate for gays from the 80's and supporting lgbt has been big part of his campaign.

Then why did he pick Pence - a actively virulent homophobe - as his VP?

i think it's insurance, really. He's a lot safer in the White House with Pence as VP.

Why are you picking on Muslims? Is there any religious group who support or at least are not against LGBTs? I also know a lot of gay Muslims (and Christians. and Jews.)

I personally don't like/understand religion, but spreading FUD is something totally different. Most of the religious wars seem to have happened because of people spreading fear, don't you think?

Even if she were, what relevance does that have to whether Trum p is "an advocate for the gays"?

Pence supports homosexual "cure therapy". This is barbaric, and quite frankly utterly revolting thing to have a VP support in the 21st century.
