In the interest of transparency - I'm leaving this up for now because it's not illegal:
Sexualising the baby would be considered rule-breaking and the comment removed, but that isn't the case here
Sexualising the act of breastfeeding (which some people think this comment does - but it's not unanimous) is perhaps in poor taste, but not illegal in itself.
Expressing a preference for, uh, certain physical traits is fine, although that may again be viewed as creepy by some people.
As mod, I'll remove posts that are illegal, discriminatory or harassing, and this post doesn't meet those criteria. Regardless, the downvotes here should be a signal that some people find this distasteful.
Feel free to upvote/downvote this post if you agree or disagree. The decision above was made based on my own evaluation, but I'll use the vote spread on this comment as an indicator of whether the community prefers a stricter policy.
