Is there a problem with marrying whomever?
Are all men & women created equal so it(color, race, gender, [insert yours here]) shouldn't matter?
Is there familial/peer pressure to marry within your ethnicity/race?
Does location play a role in your decision?
Some Nigerians oversees may argue the difficulty in finding a true Nigerian guy/girl abroad worthy of their love. (so they give up and marry whomever) - contrary others persevere and continue their search because they face possible rejection if they choose to marry just 'any person'.
i'm puzzled. I wouldn't go out on a limb and deem it wrong, but i'd prefer a nigerian woman.
