You're essentially trying to pin something on him that he never actually said. Here's the statement he made:This shit about Velma being gay in the "canon" (eugh) isn't even new, this has been reported on since as far back as 2002. This whole thing about Velma being gay just became relevant again because the new director's trying to make it seem like that this was the plan all along, with him being a totally STUNNING and BRAVE person for validating Velma's gayness by saying she was gay the whole time
even though she wasn't, but I'll get to that.
"I've said this before, but Velma in Mystery Incorporated is not bi. She's gay. We always planned on Velma acting a little off and out of character while she was dating Shaggy because that relationship was wrong for her and she had unspoken difficulty with the why. There are hints about the why in that episode with the mermaid, and if you follow the entire Marcie arc it seems as clear as we could make it 10 years ago."
He made this comment on an Instagram post which read:
"I obviously don't represent every version of Velma Dinkley, but I am one of the key people that represents this one."
I don't see what's objectionable about this. He tried to allude to Velma being gay in his show ten years ago as well as you could at the time, which you really couldn't.
