Now that I've talked them up enough, let me turn to the negative sides, and the reasons why we should be seperated.
1.) They are much different sexually than us, they believe in almost absolute freedom in this category and engage in things which are sickening to us and most other races.
2.) Their society and customs do not mix well with ours, for instance the treatment of women/children, and their almost robotic mentality in all facets of life.
3.) They are not as socially oriented as we are. You walk down a street in any major city in Europe or America, and you'll see conversations going on nearly everywhere you look. Japan or China? Dead silence amongst the people. They hardly ever communicate with one another unless necessary or they know each other well, this doesn't mix well with us, seeing as how whites are generally a very social and out-going race of people. We'd annoy them or they would creep us out, either way it doesn't make for a care-free environment.
