I have found pakistani (who is supposed hated us the most) less hostile than chinese and bangladeshi.
You can expect constructive discussion with a pakistani but other two....i think except Zabaniya don't find anyone. They just spew venom.
I have made more pakistani friends than indians...just because even if there is rivalry among us....we somehow understand each other's position, even if we don't show it, on issues such as corruption, load shedding, terrorists attack, bombing, inflation, currency issue etc.....
