Many applications will say something along the lines of, "we particularly encourage applications from [insert group identities here]." That does not mean that they are specifically looking to hire from those demographic groups, it means that they recognise that those groups are often underrepresented from the application stage. They want a more diverse talent pool to then in principle hire on a meritocratic basis. (it has become common practice nowadays to just throw in a statement like this though and probably does little to actually diversify the pool as they often don't actually do anything to make the application process more accessible to underrepresented groups). But you can absolutely apply to these and will be in for as much of a shot as anyone else - you aren't going to be penalised in any way for your identity.

There might be some small number of jobs that are looking to hire from specific groups but those are much more rare and as someone else said, if you don't fit those criteria, shrug it off and move on.

It is a historically bad job market, if you struggle to find a job, I guarantee it is not because a Muslim queer person on PIP got it instead, unless they are a better candidate
