Not a biologist, but the evolution of mammals is way more granular than you might expect. Humans are the sole surviving species of the genus Homo, which was a real party before the other ones went extinct. You're in for a fun time.

Domestic cats are believed to be domesticated not from tigers, but from the African wildcat:

Which evolved to be small just because it's sometimes more useful to be small.

And no, hamsters are not off-brand rats. They're part of the rodent order, which includes beavers, moles, capybaras, guinea pigs (yes, also wild) and lots of other fun things:

So some fanartist drew a “sexy” (read: booby) version of a (cartoon) character who is traditionally very non-sexualised. Fans of the character got mad about it because it’s kind of groundbreaking how that character is written and portrayed and this art totally ignores the entire point of the character. They demanded the art be deleted. In response to that other people said, well what the fanartist did may be distateful but they have every right to draw what they’re into. The two sides fight for days and each starts a harassment campaign and even report their “opponents’” accounts.

So far so typical. But things eventually come to a head and they decide that this will be settled by votes - not through a poll. Through donations to a children’s education charity via each side’s portal. Whoever can get the highest amount of donation wins.

one’s character has no impact on whether they were/are a victim or not, victim status is not something that is only afforded to the palatable.
