Ezra Miller

Sure but I'm talking about people who call themselves queer but aren't gay, bi, pan, trans, nb or ace and just vibe with LGBT culture.

It's a thing. "Hetero romantic, platonically bi" (ie heterosexual)

In the last 10 years we've seen minority voices be raised up up and LGBT culture in particular has been especially prominent.

Particularly in the Arts, Higher education, progressive circles and creative fields being seen "straight, white and cis" has been seen as privileged and taking up space.

People who come out especially in the creative and education sector get lots of attention and praise, it shouldn't be shocking that straight people who seek attention and praise jump on the bandwagon.

The amount of heterosexual women in particular who call themselves bi or "queer" when they'll openly admit to having no sexual attraction to women, just so they can come to LGBT spaces and venues and be the loudest voices there is wild.
White privileged objectively exists, and privileged white folks are the main ones who deny it. If Ezra was half black instead of white the coverage and Shame would be far worse
