Nassim doesn't advocate that you should become totally uncompromising toward BS as a technique to change the people with whom you hang out.

He doesn't advocate that you should optimize your tactics in that way to get better friends. He rather advocates authenticity where you don't hide by avoiding to call out BS because you are afraid of offending other people.

If being authentic means calling out BS than do it. If being authentic for you means to not confront other people about the BS they talk about, don't.
