You are right, and the answer is simple. It's inbreeding. There is a running (heh) joke that goes like this:
- How long a gypsy girl can stay virgin?
- Until she can run faster than her dad and is stronger than her little brother
Gypsies age terribly, 25 y/o ones are basically EOL by looks. I've met one who was 22 and already had these brown marks on her head that asians and "white" people usually develop around age 65 and up.
American leftists usually try to meme "whites" being inbred, which shows they never seen inbred people. Gypsies are also usually short as well, the only danger they provide is the lack of foresight which is universal among dumb people and they always roam around in gangs.
