It's this 100%. It's just political correctness.
What's funny to me about things like this is that the gay community is well aware of the risks involved with their lifestyles. There is a reason grindr (the gay tinder) is the only dating app I've ever seen that has "HIV Status" and "Last Test Date" as attributes of a profile, and that "poz" is a tag you can add, which essentially means "I have HIV and am proud of it."
The fact is that the gay community engages in a lot of very risky sexual behavior, but that's politically incorrect to say. And as a disclaimer, I am not suggesting that any of this is deserved, or whatever X-phobia I'm sure I'll be accused of for pointing this out.
