Rare archaic word. Is this common in US? And no. It is not. It's called context. It's called giving referance to what is being discussed. You claimed a fact. That is. Selective contribution is unique to Pakistan making it a 'Pakistani tradition'.
I disputed that. Now I could have said 'no' but in a discussion if you dispute somebodies claim you beef it up with some facts. I did. I have in my life seen selective accountability practiced by Margatr Thatcher in 1980s UK. USA saw it in the Mccarthy era.
Just chucking "whatabata" is merely givving of smokescrean without attending to the point I raised.
