I don't mean to be rude, but even as a trickster, Dirk had full control of his faculties, and he has made it abundantly clear that he is not attracted to women, Roxy included. He has gone on to say that, even as one of the last men alive, he could not bring himself to be attracted to them, Roxy included. I guess what I'm trying to say is that sexual erasure is very hurtful, and it should be taken into consideration when creating such a thing with a character.
Hello! I have indeed read the comic, and I understand and agree yes, Dirk is the gayest thing ever in canon (which is awesome), and sexual erasure is a bad thing.
But please take into consideration that this is a piece of fanart. If Dirk wasn’t gay in canon he would still be drawn with other dudes by someone somewhere out there (it always happens - just like no homo John is drawn with Dave; Kanaya or Rose drawn with dudes etc). It’s just a drawing, not meant to hurt anyone, please don’t take it too seriously. Fanart is supposed to be fun and show things that may or not be realistic for a fictional character.
This was a commission piece, I’m not about to tell someone their ship is wrong because it isn’t canon. This is such an old song and dance.
