I don't know if this is a joke but I think you're conflating two different things abbreviated MLM.
I mean, the "pyramid scheme" thing was definitely a pun, and I spent
way too long figuring out how to make that kind of joke work, and I'm not 100% happy with it but it works well enough so I didn't want to waste more time on figuring out a different way to make that joke.
But also, queer men (or more precisely, queer AMAB people) are often considered to be threatening or predatory in a way that queer AFAB people usually aren't. You still get the occasional psycho lesbian, but these days queer women/trans men are generally more likely to be infantilized or trivilalized than demonized.
The difference is most obvious by contrasting how TERFs talk about trans women and trans men, but it's still present when contrasting gay/bi men and lesbian/bi women. The specific attitude that lesbianism is practice for heterosexual monogamy is (AFAIK) not common outside of Japan, but the idea that lesbianism is some kind of phase that girls go through
is, as are various ways to "fix" lesbians. Gay men, not so much. Instead, you get stereotypes/joke/"jokes" about gay men being pedophiles, which isn't really a thing for lesbians. And so on.
I think it's an intersection of heteronormativity with toxic masculinity and misogyny. Women (read: AFAB people) are assumed to be objects; their stated desires don't matter, they'll become good wives and mothers eventually. Men (read: AMAB people) are assumed to be aggressive predators who indulge (or at least
want to indulge) their appetites for aggression and sexual satisfaction.
But I haven't read any feminist/queer theory, it's just patterns I noticed. I might be missing something.
