honestly, i do somewhat agree. pretty much all the characters in persona are hellla white. and the few lgbt characters are treated as jokes.
They are all asian, mind you. The only white characters are Lisa Silverman from P2 and Ann Takamaki from P5, and that fact is important to their character as they are victims of prejudice and bullying over it
That said, I can't say much for LGBT, but I will at least say the more tactful take is from P2 with the protagonist, Tatsuya Suou (Canonically Bi) and Jun Kurusu of the main cast, since they can become a thing and the feelings regardless are still canon and taken very seriously. A lot of the staff even considered this the canon romance option.
