At this point, the whole wigger argument is best left ignored. Every single point you make towards people like that is most likely something that's so obvious in logic that it'd make a lot of pseudo intellectuals try to find a point that differs from it. Obviously you can say "culture and personality aren't tied biologically to race. People are fully capable of holding indivisual identities and don't need their skin or eye color to determine it for them". But we hear that shit all the time, so that makes a lot of people want to be super cool and original and say "yeah, but come on let's get real etc". When you argue about something and make those points, it makes it seem as if it's still up for debate. That's why you see most smart people respond to threads like these with sarcasm.
