I think that is largely a difficult and expensive task, since there is no universally accepted definition of "feeling comfortable", and it is impossible to comfort a snowflake.

I'd rather be happy letting people go than chasing some elusive target in the name of political correctness. Sooner or later, I will either end up being miserably alone or with enough smart people who just get things done. I think this risk is worth taking.

There is also no universally accepted definition of "being an asshole", but nevertheless you know it when you see it, right?

Maybe some fragile snowflakes should just get over their hysterical emotional need to feel comfortable, and focus on doing real work and getting stuff done. But by the same token, maybe some assholes should get over their pathetic emotional need to belittle others, and stick to what contributes to the work.

There is a principle for robustly implementing computer communication protocols called Postel's law: be conservative in what you output, be liberal in what you accept. I think the principle applies equally well to human communication protocols.

I don't know - not calling other people's ideas at work "stupid" seems pretty obvious to me, it doesn't take some great amount of mental effort to just call things "bad" or even "not a good idea."

Also, it's possible to have smart people and a failure culture and fail. If people are afraid of posing their ideas because they think they will be shot down as "stupid", that damages your culture.

Calling “bad braindead pile of stupid shit” “not so good” devalues “good”.

Well I'm glad I don't work with you :)

A part and parcel of being a professional is being able to successfully work with people you may not personally like, as long as their and your work outputs are not being actively and measurably harmed by said personal traits.

I could probably work with you and not mind you calling my work stupid if you could also back it up. Learn something every day, you know.
