I do really like especially how you point out that homophobia and ableism manifest differently especially in the timeline of how discrimination emerges.

It really grinds my gears that fandom often acts like Sara is so privileged compared to Simon, and they never stop to examine that she has another dimension of marginalization that Simon doesn't have.

I don't really know where I'm going with this, but it makes me think about how ableism is often the root of all kinds of discrimination/hate (or perhaps the justification for it): homophobia and racism etc are based on the body being "wrong" just like ableism. And ableism is often used as a weapon to further marginalize other groups. Like society ignoring HIV/AIDS for so long, effectively disabling and further othering gay people. Maybe I'm saying that I wish there was more connections/solidarity made in fandom between characters with different marginalizations. Like wouldn't it be interesting if we could talk about Sara and Simon bonding over this feeling of otherness instead of just dismissing Sara. (so ironic that they're so ableist they can't even recognize and discuss ableism in media... anyway).
