Sorry to destroy your bubble but that's bullshit propagated by anti pandarists. Nature's fucking incel? You're a fucking incel.

1. "can only eat one thing" - ultimate evolutionary pro gamer move. Evolved to eat the super invasive grass that grows with the speed of like 1 Japanese Jesus' height per day. And what's the competition? A rabbit? Come on, pandas win here by securing a constant supply of food
2. "can't fucking breed" - myth. The fact that pandas still exist is a proof that they can breed. They only have problems with breeding in captivity, which is a case for most animals. Besides, have you ever seen a panda on tinder? Only as a wingman.
3. "can't be bothered to finish evolving" bad news 4u dude, nothing ever finishes evolving. This is not how it works. Carnivores and herbivores are labels invented by humans because we humans like to label things.
4. "we kill so many fucking awesome species" is probably the only truth
5. "but we better kill this literal icon of self sabotage alive" - we wouldn't have to keep this animal alive if we stayed in our fucking lane and didn't destroy ecosystems. And it's not a choice between keeping pandas alive and keeping other animals alive, we can do both by not being assholes. And I nominate humans as icons of self sabotage
6. "because it looks like it's dressed like a mime and it's ok to laugh at them while they look like a fat kid rolling down the hill" - yeah so what I'm not allowed to look at my cat acting funny? Or idk literally every other animal being funny or stupid? Cats do funny jumps when surprised, dogs eat shit sometimes and jellyfishes just float in the water and you're judging pandas for their pattern and rolling down the hill. But it's not a measure of animal's worth if you think it's funny or not. So fuck you.

Hum... I think pandas are kind of like humans. No?

Fuck you!
