Even Joe Biden recently said that, although he supports LGBTQ rights, he is hesitant to focus on those issues during his campaign. It is very polarizing and if he were to make his campaign about that and lose re-election, the new Administration would focus on undoing any progress made. Instead, he is showing his support and making moves tangentially by pushing women's civil rights because... who doesn't love women? These issues are less likely to draw attention from the far-right fanatics.
