/pol/ and right-wing YouTubers are just kissing our asses in hopes that we will become their allies.
The problem some people on /co/ have with the "CalArts" style is how the style is sometimes used poorly or lazily or how it's associated with pushing "progressivism". Some may not necessarily have a problem with the art-style itself, just how it has been utilized. Others just flat-out hate it, and the oversaturation partially contributes to this. I have grown to dislike a lot of 80's music because of how much I listened to it (it was on a radio I had no control over). Sometimes people just get sick of things and start noticing things that make them frown.
Most of us have a problem with Thundercats Roar because of the inappropriate genre-shift from action to comedy and the horrible first impression that the art gives. We also see how some people in the industry has handled the backlash in a very unsympathetic way. Strawmen have been used by people on twitter to denounce all criticisms with a broad brush. There has also been use of misinformation, likely unintentionally, in order to make excuses for the Thundercats Roar or the prominent usage of the "CalArts" style.
I am worried the out-of-touch artists, many of whom are openly "progressive", are going to drive people away from them, where /pol/ will welcome them with open arms. I best hope the vast majority of people are not foolish enough to fall for /pol/'s cynical agenda.
Note: "CalArts" in this case means animation style similar to Steven's Universe, We Bear Bears, and Clarence, and Gravity Falls.
