The right cares about their family, extended family, closest friends, friends, and aquaintances, mostly the extended family/closest friends. The left almost doesn't give a fuck about those people and instead claims to care about every living thing or every nonliving thing in the ENTIRE UNIVERSE.
It could be that the left are faking it cause they think that's what a "good person" would say. Or they could be absolute sociopaths covering that up with pathological altruism. Of course, they never sacrifice anything themselves, but they're happy to give away your money and your resources at will.
If you regard it [male chick grinding] as worse than the holocaust based on some twisted utilitarian calculus that is causing you to scientifically investigate pain in shrimp or calculate whether beef or insect burgers contain more qualia-per-pound, I think you've reasoned yourself into being anti-human and are an enemy to be fought.
I was alluding to a facet of this larger issue when I talked about this. I regard it as part of a largely nihilistic worldview that has reasoned itself out of believing in that which is human and comprehensible, is left unmoored and without meaning in life, and then rationalizes in sophistic replacements to try and fill the void. Some of them do this very consciously and deliberately, like Peter Singer, an academic philosopher who is probably one of the most dangerous and evil people alive (watch out for those who call themselves Utilitarians). But it's really just a larger pattern you can fall into when you deconstruct everything good in the world and reject human moral intuition (for those with faith, inspired by God) and then have to just fill it in later.
Understanding the larger worldview will help you understand what they're doing a lot better than listening to their rationalizations. Why do Green parties take the stances they do? They're not conservationist types who love their outdoor spaces and make a living off of them, they'd regard that as exploitation. PETA (with the caveat that they're popular enough that there are plenty of useful idiots in the ranks that don't fully subscribe to the philosophy) doesn't love pets, they consider pet ownership an abomination and think dogs should be "free", and they'd rather kill every last one than countenance that a human might "own" an animal. These are just people who are uncomfortable with human flourishing and industry.
If you want to see them fully self aware and with the mask off, look up VHEMt (they pronounce it vehement, Voluntary Human Extinction Movement). Null went on a podcast of someone who was involved with it, Nina Paley, who was principled enough to get thrown out of some of the circles she was running with over, if I recall, trans shit, so they had a mutual interest in censorship issues. Be assured, this is not a political thing, and it doesn't map to parties, at least not major ones since it's such an anti-human stance that it will never be truly common.
The bottom line is you can't actually reason yourself into caring about everything in the universe more than your closest human bonds, you can just reason yourself out of caring about anything. After you slap together all these rationalizations to replace your soul, at the end of the day you're just left without a soul. They assume that taking the stunning and brave stance of "fuck humanity" proves their moral transcendence, but they're just monsters, and all they really have left is the fight against the "reactionary elements" who are "less enlightened".
