If you somehow think that white men are smarter, or more capable, than everybody else, then I'm willing to bet that you haven't spent much time as 'the token white guy'. If all your experience with other races is service oriented (restaurants, banks, etc) or with 'token non-(white guy)s', then you experientially have no reason to expect as much of them as you do of yourself. This is natural. Racism is natural, just like rape, theft, and murder.
Humans: more than just a lizard brain. Act like it!
In fact, people who are raised in different cultures think differently*. From a completely utilitarian viewpoint, diversity of ideas is the most critical ingredient to problem solving. Moreover, in terms of numbers, there are vastly more non-(white male)s than white males. By maintaining the status quo, we restrict the talent pool to a tiny margin, and homogeneous dev teams get stuck in groupthink. You're trapping yourself in a stuck mindset, and the competition will pass you by.
Without diversity of eye, hair, and skin color, think of the example you're setting. When white folk inevitably lose supremacy, who the fuck is going to hire your white ass? If we get diversity up & running nice and smooth, it'll seriously work out in our favor in the long run. Make people feel welcome, regardless of their coloring. They might return the favor... but slight them, and that'll surely come back to bite you.
* If it needs to be said, culture and pigment levels are strongly correlated. Also, sending white babies to be raised in different cultures so you can maintain a lily-white workforce with a diverse cultural footprint probably won't end well.
