Maybe we respond more to the milieu of a comment more than its actual content. Personally I like conspiracy theories about topical things. I never believe them but they make me chuckle to see the world from a weird point of view. But some people are going to find such theories to be horribly offensive (like Buzz Aldrin about moon fakery). We all have the capacity to wrongly analyse something we don't understand and have no stake in. A lot of people don't know what it is like to be attracted to their own gender and come out with things that are not just offensive but blatantly silly. The rest of us no better.
