u/polcomp has an absolutely heinous comment in that chain. Not sure if I can link it directly or not, but it has gems in it like:

They're the only group in human history that managed through inbreeding to become an entirely new phenotype of human in a couple hundred years.

If they continue inbreeding at this rate they're going to reach the point where we can't even consider them the same species.

Their inbreeding co-efficients are going to approach Spanish royalty levels in a few generations and they just simply won't survive. This'll be in a 100 years time when the rest of the world is advanced unrecognizably but they'll still be living in caravans robbing steel off of buildings.

and from another comment:

I'd rather a neighbourhood of full on pedophiles and ISIS [than gypsies]. At least the pedos will be subtle and won't shout shit in big groups at your 12 year old daughters.

Mayocide when?

Edit: Shoutout to u/SiberianKarl; the only person in that chain with enough folds on their brain to point out:

they have different values which do not fit with what we call civilisation, that's all. Doesn't make them less human than you, I or people living in the Amazonian rainforest.
