Bait thread, but I'll participate. I'm about to cause a lot of butthurt everywhere, so prepare yourselves. Just remember that I hate and love you all equally, so take none of the following personally.
I hate a lot of groups, but none of the hate is because of their genetics. Hating people because of the way they're born is amoeba IQ.
The hate I have for groups is the result of their beliefs and doctrines, as well as their cultural attitudes in practice, and the actions they've demonstrated and continue to demonstrate.
I hate Orthodox kikes because of their adherence to racist theology (the idea of the Jew chosen by Yahweh and everybody else who are goyim and to be treated as cattle to serve the Jew). This religious philosophy is arrogant and perverted, but it seems to be shared even among atheist Jews. You'll see staunch and fervent atheist Jews casually using the term "goyim" or "goy." On a related note, I also hate crypto-kikes for their influence and sometimes covert takeover of a lot of institutions. They seem to carry over their tribalism from their religious counterparts and exercise a lot of nepotism and cronyism in many sectors of society as a result. All of the "Jews control everything" memes are based in some truth.
I hate niggers, because that's a cultural and racial identity embraced by many African Americans and even many other westernized African immigrants that centers around gangbanging, murder and drug dealing. Degeneracy, basically. And now niggers have carte blanche to do literally whatever they want in the US, free of consequence, because one criminal black guy got murdered by a cop, and if you call out their bullshit and criminal behavior you're a racist. Many young blacks act like niggers, then get upset when people treat them like niggers. *pikachu face* What's worse is that they call each other nigger like it means "friend and brother" and get mad when somebody else calls them that, without being aware of what it really means to call yourself a nigger.
I hate honkies, both Europeans and Americans, not only because of their imperial and colonial legacy, but because they've enabled modern degeneracy. They also have a terrible habit of sticking their nose into other peoples' business through all of these wars and invasions trying to spread "peace and democracy", while secretly stealing natural resources, and think they're morally superior and righteous in many instances. The Absolute State of the World 2020 can be blamed mostly on white elites (with the assistance of the crypo-kikes). I also hate them because they're absolute CUCKS in some countries (Sweden, UK, Canada, to name a few) that would prefer their own mothers, sisters and daughters get raped by immigrants, than to offend their own liberal sensibilities.
I hate sand niggers, because, like Jews, they're arrogant and have this "Arab pride" that seems to leak into many other aspects of their life and personal identity. It doesn't matter if they're a literal janitor, they will think they're better than you. Their arrogance probably stems from the fact that their people were never enslaved historically. This arrogance is partly what's costing them in their own lands so severely. They'd much rather think their tribe is better than the one next village over, than unite and fight the common enemy. And every single Arab driver I've seen on the road is literally the worst fucking driver in a ten km radius around them.
I hate chinks because because they have the cunning of the Jew and arrogance of the Arab, but you'll never see it on their face or hear it in their words. I hate Indo-Pak curries for the same reasons. On that note, I don't think I've encountered a more overtly arrogant attitude than that of the Indian. It might be a cultural meme that's been imprinted as a relic of British colonialism, but I can't be certain.
I don't have much experience (both positive and negative) with spics, wops, wogs, gooks, and other groups like slavs and Eastern Europeans, or even Central Asians (Turkmen, Kazakhs, Armenian etc.), so I don't have any particular hate (or love, but this is a hate thread) for them. Maybe somebody else can fill me in on those particulars.
tl;dr: Humans are generally terrible.
