it is not blatantly bigoted. It's just a fact that applies to all minorities.

I see more people in wheelchairs in my day to day life than I do lgbtiq people, albeit still only a few. Both exist. both are a minority and both are not that way by choice. I don't hear wheelchair bound people complaining that there should be a lot more wheelchair bound tv and movie characters. It's not like there aren't any (professor X, for example), but there aren't much, just like real life.
