only attracted to queer people?

I would assume that it is the way they carry themselves.
Queer people can have(not all of them) a certain way to dress, take care of their image, talk, show perspective into other people's point of view and lives, be confident or even fearless because they stood up to criticism for years.

This does not apply to all queer people, but it may apply to a certain category of queer and queer-supporting people that participate in a certain culture or share a certain generational background. If you are attracted to these people, you will notice them more, whilst you won't notice other types of queer people.

Same applies to straight people.
A lot of straight people who talk about straightness and gender and gender roles, appear on tv and in movie roles and they speak a lot and they are everywhere. And I can't stand them. But they are not all straight people, by far.  In fact, in real life, it takes a whole while longer to get to know them or spend time with them, but there are so many straight guys that are faithful, open to self-expression in a partner, not confined to a tiny ego box. And many straight girls who are bosses on the job, very competitive or they have ''non-feminine''(whatever that means!) characteristics like being superficial with sex, narcissistic, or sex-obsesses but deeply affectionate and whatnot. There is the whole variety if we look at individuals and not at the models of how we should be because we have x or y inbetween our legs.

Going back to your post, I definitely remember a time as a teenager/young adult where I was only attracted by butch lesbians in girls.
I am now attracted by people who very often happen to be
- gay guys (not all gay guys, in fact I can't stand just as much guys who are also gay). I fancy the nice ones who look bomb because of their style and grooming and are chill and sexually driven. Like myself! lol and not super vain and shallow.
- straight girls who look bomb because of their style and lush hair and either follow their own dreams/path unapologetically (''they know who they are'' and they act on it) or are into sports. Like I would like to!
- bisexual girls, as above.
- bisexual guys, I fancy almost all of them(at least the very few I met! don't know about the ones I don't see). I generally guessed they were bisexual and it was then confirmed. good bi-radar, sometimes.
- Lesbians who are masculine behaving but not psychopathic(too cold and shallow). If they act sporty or manly or even better playful and assertive I'm sold.
- Straight guys, when I like them I like them a lot. Unfortunately, many of them are completely unaware of queerness, of the fact that gender roles are not necessarily everyone's cup of tea in dating and so on. Often I am misunderstood by straight guys, who can see me as either a sexual object with no dimension(really depressing ..they don't empathize at all with me, while I do with them) or a masculine unstable weirdo who is failing at being the feminine goddess they deserve. The straight guys that I liked have always being much more shallow and vain than the queer people I fancied. They seemed to consider me a trophy or a tool to use for their confidence, rather than someone like them. But again, they are not ''all straight people''.

Sometimes we are attracted to a certain cathegory/subgroup/culture because we like what they represent. It is all yet to be confirmed if they, and only they, actually represent it and are good people for us. Nothing wrong anyways, just more investigation/experimentation/relation/mixup required.
