because muslim countries is shit and there is no white pussy with soft pink nipples. All migrations and wars is always about that after all. Wealth and pussy. 
tell you honestly, i am not ethnic russian,i am tatarian, i lived whole my life with ethnic russians around. My situation is like:i dont look russian and russians never take me like one of them, but my mentality and behavior is 100% russian so i never considered as tatarian or even,i will say, muslim near muslims or tatars and etc.What i want to say is that i had couple of muslim "friends" who didnt know that i am russificated tatar,and we have some freedom of speech between us without this cultural borders. 

What did I understand from talking with them? For them white pussy is ultimate goal.I mean, muslims still have some sort of medieval marriage, when desigion about marriage is taked by parents.So all good muslims girls is always "taken" by "alfa" dudes or famalies, and all rest girls.. well muslim girls in general ugly and etc, so this is some sort of second grade. And here we have white girls. Infantile, from families without a medieval way of guardianship and good looking especially if you compare them to second grade "muslim"( tatar or -stan shitskin etc) girls.So white woman is some sort of booty for them, and the relation to them corresponding.So, when i see white girl with shitskin or muslims boyfriend/husband etc i am 99% sure that he probably beats her,and etc. 

Muslims are like niggers in general. And on the other hand white countries in general have a problems of unproportional ratio woman/man, i dont even talk about social problems like feminism or s.o.y.boyism and etc. All this problems kinda force womans to date with this muslim animals. And what very important - muslim dudes are most likely have CHAD behavior. They lie as they breathe , constantly. And womans are very vulnerable to lie as we know here. 
just some thoughts on this topic, but i did not even disclose the rudiments
