This has zero to do with Trump and everything to do with the way we view humans. I hate it when people say the KKK, slave owners, etc were animals. They weren't! They were humans that did terrible acts. The reason I personally don't call people "animals" is that it can change your view of how you'd like them to be treated next. The word "animal" allows a person's mind to accept inhumane behavior to being done to them.
I used to call terrible people animals years ago, but I've learned to not think that way.
I don't personally like to call people animals either. I don't like to call them monsters. One reason I love Twin Peaks is that they show how good people can do terrible things and people who do terrible things can still be loved. But I understand really well if someone wants to call, say, a person who tortures, rapes and kills someone an animal or a monster. I personally wouldn't necessarily say it, but I definitely understand people who do.
If you do inhumane things to others, you should be prepared the same happen to you. Not that I advocate physical retaliation for crimes or that I encourage people to take law on their own hands, but if someone goes and beats the hell out of someone who has raped and murdered their child, I wouldn't have any sympathy for the rapist murderer. I wouldn't go and say, or even think, that this rapist has been handled wrong when the father of the victim beat him up.
That said, I will wholeheartedly applaud people who can and will forgive even people like that, like the father of a victim of Gary Ridgway - he forgave Gary even though his daughter was raped and murdered by him -
this video still brings me to tears - and in that video I can feel sympathy for that "animal" because of his reaction to that forgiveness. See, people with an "animal status" can be loved. They can change. They can show regret. But it doesn't change the fact that their behaviour has been horrible and disgusting to the point that it defies all what we think civilized humans ought to be.
I wouldn't understand someone calling someone who grab's someone's butt without a consent an animal. I wouldn't understand someone calling a thief an animal. I wouldn't understand someone who punched a person who then fell down, hit the head to the ground and died an animal. I wouldn't understand someone shooting a person during a robbery an animal. But people who torture, rape and murder, saw people to pieces, drag the corpses for people to see, burn people alive, that kind of inhumane acts are something that goes beyond "normal" crimes and bad behaviour. And I will not say one word of criticism towards people who see them as animals. You act like an "animal", you deserve to be called an animal. You don't have to be called an animal, but if someone does call that person an animal they've reaped what they've sown.
These people are already the lowest of low in people's eyes even if people wouldn't call them animals. As if that word would make them suddenly think they are lower than what they already think they are.
I wouldn't say there are people beyond redemption but some are very close to that. And I think it's pettiness in it's highest form to call out people who go and call those people animals. Calling someone an animal is really damn low in a list of unacceptable behaviour. They have murdered, they have raped, they have tortured and they don't regret it. They sure as hell deserve a punishment of some sort. They at least deserve to get their freedom taken away. Like, what, people call you less than a human? Too bad, maybe you shouldn't have participated in torture, rape and murder and maybe you at the very least should've shown regret about it.
And once more, no-one thinks they are not-humans. The "animal" and "not people" means they are humans and they are people but that their acts are as if they weren't.
Someone should make a comedy sketch where a person who has tortured, raped and murdered people gets sentenced for life and maybe even gets a death sentence on top of it, but when someone comes and calls him "an animal" there's one person who steps ahead and starts saying "no, don't say that, don't call him an animal, that's uncalled for!" As if calling the criminal an animal somehow makes the criminal's situation worse. As if calling someone an animal goes over the line after sentencing to jail for life.
