It's called being professional. Your coworkers don't exist to be a sounding board for political, religious, or overly personal topics. This is just the baseline. You don't need validation about that stuff to do your work. Pushing people out because they don't have the same "vibe" is counterproductive and makes everyone worse off.

If you told kids in school the truth, it would be that juvenile attitudes die hard. Adults are too often like big kids. Looks and superficial stuff still matter a lot, although you can still get admitted to companies if your job requires actual skills or characteristics that you have.
