Gay people discriminating against Transexuals is also logically consistent (not Moral, but certainly logical for somebody whose thinking is “As long a I am alright”).
For me a logical explanation for some people who are Gay aligning themselves with Trump and their crowd is them thinking that the prejudices of those people are against Transexuals, not Gays, and as they do not see themselves as being the same and they’re not actually pro-Equality out of Principle but simply out of “what’s in it for me”, they’re ok with discrimination against Transexuals.
