The thing is, we're not all equal, and no amount of wishful thinking is ever going to change that. There will always be favored in-groups and disfavored out-groups.

What'll really mess with your right wing sensibilities is that equality, happiness and ranking high on various democracy indexes all correlate. Arguing against happiness sounds just weird.
Ah ok, so your goal is literally to have second-class humans. Or do you even consider them human? Okay. I wasn't expect such an outright admission. Wow.
