I think the main point of contention would be that MLP is basically a feral world, and a lower level of anthropomorphism than usual can make people uncomfortable.
The other potential reason that people might not have responded to your other post is that... TGTF and forced-feminization aren't really related to mpreg. Trying to write stories or world build around a fetish is fine, it's just that those aren't the main fetish the thread is catered to. There's a difference between "men can get pregnant because [insert worldbuilding here], and this is how society would react" and "Traditional sexes no longer exist, and everyone is gynomorphic. All women are futas or herms and all men are sissy femboys/cuntboys/maleherms. Also """male""" pregnancy is possible-- whatever that means in a world where distinct sexes are meaningless." You do you, but it's plain to see that the focus and intention are completely different.
I'll throw you a bone, though, in . If, say, mpreg was possible in the MLP world, and the Gala was a big orgy instead of a supremely boring party for the members of high society, you might find the refreshments full of aphrodisiacs or stamina boosters, to keep the party going long into the night. Clothes would be less formal and more fetishistic (not that that's saying much in a world where full nudity is commonplace)-- and would leave both the flanks and belly uncovered to facilitate the breeding. Sex toys and lube would be party favors, and you might even have certain brands endorsed by royalty, like Wedgewood Queensware for pottery. You'd have a fair share of fans, would-be socialites, and general gossips following the proceedings like people watching any given show involving celebrities in our world-- taking note of who had gotten knocked up, by whom, and with how many. Culturally, it might even be considered classy to be born in a certain month, because it would coincide with when all the royalty, famous sports figures, and so on had given birth after being knocked up at the party.
