Lestat disrespecting pronouns makes complete sense. Lestat is a misogynist and has a billion layers of internalized racism. His scope of empathy is confined to his own identity. He will challenge homophobia and any criticisms against his identity and choices but he won't do the same for others.
Like we saw that man dismiss Louis' very valid anger at the white businessmen in Storyville. He didn't lift a finger to actually help in a meaningful way, and when Louis killed Fenwick(?), his reaction wasn't to reflect on why Louis chose him of all people to kill. He thought Louis had gotten around to killing, which is blatantly not the case. Lestat did exactly what he did with Louis; say surface level things and commentary while not behaving any differently. That is literally the root cause for why his relationship with Louis fractured.
He loves Claudia but it's the same with her too, he never saw how her race and her previous experiences as a human impacted her ability to trust and function in the world. I know the whole train interaction is being challenged as a complete lie, but something Lestat did made Claudia feel like he saw her sexual assault as trivial.
Lestat in pop culture is a queer icon, a symbol due to how much he deviated from that time's norms. But in-story he was still rather, I don't wanna say conservative but, more conforming than you'd think.
