I find that when I come across comments or jokes that might expose biases, rather than interrogate the person you can expose those by just asking the simplest questions, the ones that seem too obvious to ask. When someone says a joke that might be described as biased, usually using a more particular word, just ask them to explain the joke. That usually is more revealing than calling its speaker a name.

So, I don't want to infer your opinions, but I want to ask: what about social justice and diversity is to the detriment of their software?

This is led some credence by the fact that the Tails website links to riseup.net, which hosts Rose City Antifa.
