Which is to say, there will never be a single truth for these topics. So why not build a mindset that is ready for encountering differing opinions, diverse code?
Invalidating people’s coping mechanisms without proposing your own never goes over well. And sometimes even then.

If you don’t do any of these things, then it’s challenging to have empathy for or understanding of the people who do. The people keeping the wheels on deserve the benefit of the doubt. In fact anyone who will stand up and fix problems when they arise deserves a bigger vote on how things get done. Everyone else’s opinions are theoretical rather than vocational.
