The AI hate comes from fear of misuse and replacement, which is exactly how game engines, the typewriter, And even the Internet itself were treated, if anything it's not AI-slop that's the problem... it's the hivemind slop.
I'm an artist too and I do game design on the side, I don't use AI to make my works, but sometimes I'll use it to aid it like any other tool.
Such as the animating your own art example you gave, because not everyone can animate... and yeah on the surface the "Just learn how to animate!" Idea seems right, but it's an empty wish from non-artists who actually don't understand how the creative community works and pretends they do.
People cannot realistically become a jack of all trades, and unfortunately people like OP are being punished for using the tools needed to appease the current generation that has the shortest attention span and the biggest gripe about things taking too long, yet they hate on people trying to catch up with them by using the tools necessary to do so.
You can't have your cake and eat it too, that's not realistic thinking.
Besides most of the people who claim to hate AI don't simply hate the AI... They just want to feel superiour over the AI user because "I'm a traditionalist!" So really the first guy who replied to you is simply trying to flex, not protect anyone.
If the Internet wants us to stop using AI to keep up with their fast trend needs... then the Internet needs to slow down again like the early 2000s, otherwise it has no business complaining.
Ps. OP stated they can't financially afford everyone to do the things they can't do for them, if you want them to make non AI related works then you better start putting your money where your mouth is and donate to them, otherwise again, don't complain if you're not even going to fix their issue and just yell at them for a superiourity flex.
