I try to avoid such type of people:
Only- me-nationalist (literal fascists)
People whom i avoided earlier (avoided for a reason)
Sinners and on that best kinda preachers
The guys who bark about gals (loosers kahin ke!)
Oh yeah! Especially the ones who say i know her so well since blah, blah, blah time; hardly matters you are not in touch since decade/s and even then did not like them!
And if such people feel that I am arrogant, well who cares!! I think it's better to be called arrogant than taking unnecessary headache!!
