I think his experience of racism and "shitboy" may have desensitised him to the whole thing. He was there for years before I joined and honestly, it was meant to be better then and had a bunch of work on the culture but it was still pretty shitty.

I remember once I semi-joked "You guys talk about a culture problem in IT, it sounds like you have a Tejas problem" and he generally looked like he felt bad about it.
