"We wuzzery" is the short form of "we wuz kangz," which is black people claiming that they were the ancestors of anyone that's ever done anything in history, such as Egyptians, Mozart, Israelites, the entire island of Briton, etc.
Lately I've noticed some right wingers on X trend into the wuzzery as well. For example, the claim that ancient Chinese emperors were white has been doing the rounds for at least a few months. This is based on remains called the Tarim mummies that were excavated in Xinjiang and exhibit red hair. So it seems there is some basis to this... until you look at a map and see that Xinjiang borders Kyrgyzstan in the northwest and wasn't even really part of China until recently. So we're talking about white mummies found near the Caucasus. Earthshattering.
The other claim, and probably weirder, is that Jesus was a white European. I understand the motivation behind it - Christian heritage is a significant factor in today's right wing, but due to present views of Jewish culture the idea that Jesus was ethnically Jewish sticks in people's craws. Also, this countersignals the infamous kangz idea that Jesus was black.
Unfortunately there is no evidence that Jesus was white in the European sense and the Biblical record in Matthew and Luke clearly states via genealogy that He was born to the tribe of Judah. ("Jew" means member of Judah.) Revelations also calls Jesus the "Lion of the Tribe of Judah." In terms of appearance, that would be something like the modern Lebanese.
I guess the lesson here is that even anonymous discourse can tilt away from the facts when under cultural and political pressures.
Ignoring for a second that Jesus Christ was the son of God, he's described as Galilean. Even today, after two more millennia of interbreeding with Arabs, there are still Galileans with blonde hair and blue or grey eyes. The picture that's been floating around the internet for 20 years that supposedly depicts how Jesus "really looked like" (and apparently it's like a fucking Cro-Magnon Saddam Hussein) is reddit-tier junk science.
