From a purely psychologic standpoint, I am guessing that the difference of reactions is because most people here are (heterosexual) women, so they tend to identify with women more than with men and only see BL as a way to waste/spend their time, while MF romance is more a way to immerse themselves in a story, and identify with the female lead (not like you can't identify with someone of a diff gender, but it's obviously easier if it's the same gender/sexual orientation as yours).
So I do agree that these plots cause more uproar in MF manhwas/manga than in BL. However to say that these comments are not present in BL is a stretch. I would even say that there are somehow more people defending the ML in these stories than people defending the ML in BLs like Jinx, 2020, etc... where the character commiting SA gets arguably more bashed (though the stories are still very popular).
I just know he the type to ask for the husband stitch without his wife's consent. Ngl some male leads can be kinda hot with their teasing, but he's just straight up cringe and disgusting, even with that face.
