This is a case where two blatant truths are hard to swallow together.<p>1. People define themselves via their career and their hobbies and these are often correlated with certain races and genders. This gives rise to a kind of social-gravity that attracts those type of people more than others.<p>2. People prefer to work with friends.<p>Taken together you can have highly homogenous companies that were built from the group up without a single racist or sexist thought. So its not as simple as &quot;I&#x27;m definitely NOT a racist.&quot;
