My favorite is Bog king from Strange Magic - Has a song talking about how evil he is. But all he does is prevent the spread of dangerous mind control magic, and quarantine people under the effects of said magic. Yes he greatly annoys people doing so, but honestly? If I get hit by a love potion, please quarantine me.
That doesn’t make the criticism invalid.
You have a right to critique any aspect of any work.
To me, this is as silly as the people who were offended when the Green M+M changed her shoes.
