The thing is I do consider Simon's misogyny to be a part of his gay-coding/gay readings of Simon because there does feel like there's a bit of a difference between the way Simon exhibits misogynistic behaviours versus men around him.
Let's take Hank McCoy as an example. Hank was written as being a misogynist until roughly his late 20s to early 30s and a lot of that has to do with yes, changes in notions of feminism as his comic history spanned decades but also a certain amount of growth as he experiences rapid de-gendering via becoming a mutant who doesn't look human. Particularly in the LeeKirby days, he is a misogynist the way Hawkeye is a misogynist, which is to say he genuinely is a misogynist in a way that is meant to be unappealing and off-putting, not just in a period typical sense.
It's played for comedy but still a part of his early character that isn't helped by him calling women females very often after he becomes more intellectual.
But while Hank is a misogynist, he's a misogynist in a way that clearly does see women as attractive, but he is viewing Jean and by extension, other women as a goal to be reached, and not as people to form connections with. This is a very normative depiction of misogyny and is the usual one most comic characters get.
Hank does grow from this habit and I think part of that is joining the Avengers and being around women like Janet and Wanda, both of whom are Stan Lee originals so aren't necessarily the best showcase of feminism but equally are being written by Steve Englehart by the time he joins and so they, particularly Wanda, have a bit more grit to them than LeeKirby era Jean was afforded and wouldn't really get until the Claremont era, and so Hank is forced more to deal with their personhood and individuality, also in part because they're both married when he joins the team and so he never sees them as things to be conquered, but as teammates he respects and is deferential to.
Simon though, doesn't really get that same framing of misogyny? With the exception of Wanda, who is definitely someone Simon sees as a trophy he wants to achieve, Simon never seems particularly into women or is casually attracted to women in the same way. Like, when he meets Carol for the first time, in her original midriff suit no less, he's emasculated by her.
She thinks he's cute, but I struggle to read Simon as anything other than frustrated and again, emasculated by her here. It's a completely different vibe.
Like, Hank is friends with Jean but he also has a sometimes generic appreciation, sometimes crush for her that impacts their relationship and the flavours of it from time to time. I would say the same of his relationship with Betsy or with Storm, where he does not outright date those women but he is still into them and thinks they are very beautiful, attractive women who happen to be his close friends.
And Simon doesn't really do that ever! I'm scouring my brain trying to remember he made an offhand flirtatious or sexual comment to someone and I'm really struggling. I'm sure there's something somewhere, but really outside of Wanda who does kind of make his character collapse because it's such a half-baked dynamic it just isn't a part of him. Because he doesn't like women. Both in the misogynistic and gay sense.
