Why are White people so aggressive and combative compared to the rest of the world?

I think it's about how we got our white skin to begin with. We kept moving northward until we needed different pigment to get enough sun into our skins to survive. So, the people with darker skin couldn't survive in the more northern Climates (this is one theory). However, then there are eskimos who fit another pattern and likely migrated from Asia during the last 15,000 to 20,000 years when the oceans were 400 feet lower than now. However, now they could be 16 feet higher or more this century which will put major parts of all seaports underwater worldwide.

So, unless white people were agressive in trying to survive the winters they didn't. Another cold weather adaptation is penises that don't freeze off in cold weather like black people's penises would in colder weather before modern heating technology. So, penises that retract and scrotums that retract to stay warm enough not to freeze off was another adaptation like white skin.

But, white skin is much more vulnerable to skin Cancer if they move south from the more nordic Climates too.

But, the agressiveness of white people I think started just trying to survive where it snowed every winter. So, we are more adapted to surviving in colder weather than many other races. However, with modern heating technology any race can live any place now so this is no longer a factor where there is enough wealth to live in a fully heated house in the winter time where you nuts weren't literally going to freeze off because you couldn't live indoors next to a fire yet. 

However, this is just one person's opinion of someone who has studied Anthropology in relation to all races, especially cultural Anthropology. I have also Studied Comparative religion as well.
