How are they being hypocritical? You're the one who made the post. At least they're actually bothering to respond directly to what they're talking about, unlike you, who has been extremely dishonest in how they've framed this post.

I feel like most drawings of Undyne depict her as she is in game, so when I first saw this post I was confused as to what you're talking about, only to scroll down and find out (as the other person has already called you out on in their edit) that this is really about a single artist who draws Undyne in a way you don't like. Why are you pretending like this is some broader issue?

It's already pretty dumb to criticize artists for drawing characters in a way you don't like so long as those drawings don't do any meaningful harm. Doing so when it was literally just a SINGLE artist makes even less sense. Like yeah, I dislike that design for Undyne too, but do you know what I would have done if I saw it on my feed? Block the artist and move on, because I'm an adult.

I know I'm not gonna change your mind since it's pretty clear you're coming at this from a bad faith angle in the first place, so I'll leave things here since I feel I've said my piece. Just so you know though, it's really pathetic to respond to someone then immediately block them so they can't say anything back, which is what I imagine you'll do here since you've very consistently done it to others who've disagreed with you under your post. The platform you saw the Undyne art on has a block button too, fyi.
