Can somebody here explain haplogroups to me?

Haplogroups. They are DNA genetic markers in the Y dna. Im not entirely sure what they are exactly because im not a biologist.

But in western Europeans, the R1b haplogroup is dominant.

Blacks have more chimpy genes so they are stupid monkeys.

A pure subhuman nigger I am talking to right now, nigerians are the most primitive looking niggers on planet earth.

Hey, I wish there were a good resource on such a thing, but, does anyone know if there's a website where it's a database that ranks haplogroups (specific ones, not just "J" or "K", but, J1e, k1a1, etc.) by frequency, both over all known data and ethnicity?

Like, if I wanted to find out the most common Y haplgroups among Ashkenazi Jews, a list would read as Follows:
Ashkenazim (Y):
1. J1 (11%)
2. E1b1b1c1a (10%)
3. J1e (8%)
and so on.
I'm making these numbers up for the sake of explaining, but is getting the data this organized and specific even possible?
Pic semi-related--It's on the right track, but doesn't have specific ethnic groups or haplogroups listed.
