I just recently saw a conversation about this exact topic! One man said
something along these lines: they don’t put people of opposite genders together randomly because people wouldn’t be comfortable with that. And why? The only reason is the potential for sexual attraction. So, it follows -this is still him - that they shouldn’t randomly put a male who is attracted to men together with a man. He said he would be uncomfortable with a gay male stranger as a roommate, not as a friend, but as a roommate.
So, yeah, there are people like that, so like some people said above check with housing and make sure they’re putting you with someone open to sharing with someone who part of the LGBTQ community.
