I'm not saying that what you've said is intrinsically problematic. I've said variations of "baby [object]" as well, there's nothing wrong with that. The issue is that context matters, and in this context it's condescending in a way that prevents open discussion.

Any reasonable person would read what you wrote and interpret it as "do you think the show is bad, or are you inexperienced and like baby things?" In this specific case, I do happen to agree with your opinion on the material. But if there exists someone who does happen to like the show, they are now discouraged from commenting and sharing their opinions, because you have pre-emptively denigrated their views.

Starting a discussion (it's a discussion community, after all) requires more care than usual to ensure that you are fostering a fair and open discussion. With the way that the post is currently structured, I don't foresee a way that a fair and open discussion can be had.
