Just to clarify, I did not say 'all', i just said that most do. Then again i am basing this from my own personal experience in interacting with the Chinese members in PDF, this is just an observational analysis. Perhaps Im wrong. Anyways, i have no issue with people who may disagree with me (or for me to disagree with others), the only issue i have is when people start hitting below the belt and resort to personal insults. AND those who resort to personal insults and invective uses are "awarded" with support "likes". For example, member 1 will use a racist term referring to Japanese, instead of being corrected, other members of the same nationality will actually "cheer on" or "like" the racist comments. Just doesn't make sense at all.
For me, call out when someone makes a wrong. Correct it. Move on.
But that's just my gist on things. I guess we all are raised differently and have different perceptions of right and wrong.
