This is admittedly a tangent, but I think that there is enough overlap to make it worthwhile.
What is wrong with people? This is an artist who needs to have some sympatico with what they draw. If they are not interested other artists can do a good job with gay male and transgender art commissions.
I really doubt that it they had another job of cleaning gutters they would not do that for gay men and transgenders.
This is an artist. I have no problem with creative people setting limits on what sort of content they are willing to create.
