MacGregor being gay
We're supposed to know he is, so it *seems* obvious enough.
The whole "my interests lie elsewhere" scene. We know he's gay, it's pretty clear. But that's the most he ever says, he never just literally says "I like men." But it is clear, especially given later remarks of "would you like to bite my stick?" and "shall I pop behind and give it a once-over?"
So you know, that somewhere, there's a white racist homophobic mother who's telling her kids "That just means he wanted to date a girl who wasn't white and his parents didn't like it." Which still equates to "racism is good, and homosexuality is out of the question"
Exposure isn't worth much if it's ill or vague
Why representation's important ;)
