Is Richard Dawkins still a humanist?

I am trying to understand how he disrespected the trans community with what he said

I just read up on what he said and it seemed fair. He said in earlier comments he'd still call a male who identifies as female, a she but by chromosomes they're technically still not female.

yeah, only 25 years after they gave it to him, and because he said stuff about transsexuals and I thought you be happy about offending transsexuals
