>>94346493That's not the point, really. Bart's core character concept is being impulsive. He has no conception of a society where being gay is bad. If he had gay urges he would act on them immediately because he's Impulse.
He doesn't have gay urges so he doesn't act on them. He's not gay, or bi, or any of that and he's not a character you retrofit "coming out of the closet" bullshit onto.
If you want a gay speedster gay up one of Wally's kids.
