ah yes, the perfect excuse to build his harem "i don't like how men look at my mom"

Also author-artist conveniently drawing the most burliest men leering disgustingly and very obviously with ulterior motives at his mom.

I would believe more that in time periods like this where they still have class distinction and "slums", most slave men, guards, mercenaries, and men who weren't high-up in the aristocracy were not as subtle when they were "leering" at women.
Like yeah stories with the handsome male leads are nice but for every hot guy, there's like 50 normal guys who aren't as nice to woman and children somewhere in the kingdom.
Especially when the story starts off with MCs dad knocking up multiple woman for heirs and the slave woman background seems from her daughter getting murdered by a man who couldn't keep it in his pants.
