Do people really hate mpreg THAT much?

So I posted a chapter about 10 hours ago and went to sleep. When I woke up, I had 12 comments. 9 of them mentioning "ew, mpreg" or "why wasn't this tagged?".

Did the guy in my fanfic get pregnant? No.

Was there a pregnant guy in the background? No.

Did the characters talk about one of them wanting to be pregnant? No.

Was this the Omegaverse? No.

The characters were talking about yaoi, and when one asks the other what the manga is about, the response was "character A is pregnant and then they raise a child together". End of story. Nothing more.

Of course, I deleted the comments and muted those who wrote the longest and rude ones, but I feel like I'm going crazy.
