I'm mexican and pretty much the only ones who care about LGBTQ+ issues here (whether to take it seriously or mock about them), are like less than 25% people from the upper classes and even less people from middle class, and let's say, that from those people who care, there is a majority of people (mostly above 30) that are against these ideas.
This without mentioning that most people don't even know there are such terms as "transexual" or "queer"; in fact, I didn't know about the TQ+ until 4 years ago, so in that regard it wouldn't surprise me if someone from Mexico (I dare say all Latino America) took this topic as something "funny" unlike people form the States or Europe, which I perceive, are more "educated" on this regard.
Just something I thought worth the talk when dealing with people form other countries on this topic.
Although from the comments of this guy, it didn't seem to be the case, and for the comments he received before saying the "comedy" thing, I don't think there's a real reason for him to answer like that besides being edgy.
I might be wrong though, but I didn't perceived it as such.
