Were I black or gay or trans or a woman and American reactionaries are threatened by me for existing, it is not a choice. When your existence is a political question and a political threat, it is not so easy to simply "take it easy".
Everyone else is at risk, but white men are some homogeneous group that bands together to hold everyone else back. Do I have that right?
edit: I'm trying to get away from arguing with anecdotes, but let me share a more extreme illustration of how a Christian might also feel "threatened" since you clearly already empathize with the gay community and why they feel threatened. A while ago the library in the next town over hosted a "drag queen story hour". They explicitly advertized this as being an event for children ages 2-8, where kids could come and read with a drag queen. The library said this was to promote diversity and understanding. Obviously the bible thumpers lost their minds, and the library then pulled one of the performers from the event, citing concerns about that performer being bullied. I googled that performer's name as part of trying to figure out what this was all about. The first thing I found was a video of that person, outside, in public, in a major city, masturbating with a toothbrush. The second thing I found was that person in lingerie kneeling before a Christian statue with what I assume to be simulated ejaculate on their face. This person, using the same stage name, was being promoted by the local government for a children's event. And objections about the appropriateness were labelled as bullying. If you're an otherwise peaceful, church-going person who has not previously been much of a party to any LGBT discussions, do you see why these people might feel like there's a threat to their way of life as well? And why they feel disrespected? There's not a lot of openly gay people in this town. This, and media, are all the exposure any of them gets to alternative sexual lifestyles. I don't know how you come back from something like to a reasonable discussion about the real bullying that happens.
