Yes indeed. I actually read "feminist" research because its useful to know your enemy, and often its the only research on a topic. It is indeed remarkably rare that any of it bothers to actually include males. When it does it frequently produces "surprising" results (what are in fact contradictions to the feminist hypothesis). In a recent flurry of such stuff has been the finding that young men are becoming skeptical of feminism. And this brings on lots of panic and claims of misandry, yet actually what it shows is even in young cohorts the majority are for equality and the older cohorts remain broadly positive to female equality. In other words men are overall not remotely "misogynist" as feminists claim. As shown by their own data!

I really do think the absence of asking males in any concerted way is because when they do the results are "surprising" and consistently refute the feminist narrative.
