There is totally such a thing as objective morality,

Well that explains a lot as to why we've been disagreeing.

Did you miss how I said that if people don't listen, it means your speech is boring and nobody cares? It's harsh but true. If people only listen to you if you paint Sans over it, then they care about Sans, not what you have to say.

It's not just simple venting when it ends on a command to do something. That's the artist trying to make a difference.

I agree that it's fine to use canon characters to make points. That's why I said to they should have made good, elegant comics that ingrain their ideas. This comic didn't - they with used a canon character as mouthpieces to give their own speech and there certainly is something wrong with that, in my opinion. It's disrespectful to the source, for instance. Anyone who cares about Sans will look upon this comic with disgust. I notice you switched "shitty" to "crappy" earlier - well, the comic artist here had Sans say "shit". That's the poor level of care given to Undertale in this comic. It exploits the creative characters Toby created and it exploits the emotional connection readers have with them in order to essentially spread propaganda. That's exploitative and manipulative in a pretty bad way. The comic shows no love for Undertale and no care for the readers. It's shallow and aggressive. It's bad, and using Sans as a mouthpiece was bad.
