Why can't I defend yuri smut?

It's about manwha Lover's Hell, and it's just silly trashy erotica about a masochistic housekeeper being a sex slave for two sadistic sisters. It's stupid, but there's a bunch of stupid smut here on mangago, and I actually like this one and I think it's getting too much hate, people saying it should be taken down because it was written by a male?? Like should all yaoi smut written by women (most) be taken down too then??
Anyways, this is what I tried to post over there, first as a comment, then a topic, many times, and it just disappears when I reload the page:

"I'm sorry but I don't get why people hate on this so much? Is it because of m/s and d/s being a big part of it, or is is because it super smutty without much plot? I get that may not be everyone's cup of tee, but you can always find something more fluffy, vanilla and plot heavy, there are many such yuri out there. Asking for it to be taken down is too much, don't yuck someone else's yum. As a horny masochistic lesbian I absolutely love this, and I don't really care if it was a man or a slug who wrote it. Shame Application is pretty much a yaoi version of this and it didn't get nearly as much hate. And I don't really need more plot, my brain hurts enough already."

Like, why? is it offensive of something?
