its definitely many of them from what i experience as well and yes, tons of people immediate resort to personal attacks. but i've learn to ignore the most silly ones, and i have read many of your posts, you seem like an alright guy.
I have high appraisal of Chinese people, Chinese society, and Chinese culture, generally i would say i have a deep love and fascination for China and the society. Tho I may not agree with state policies of the CCP, that does not mean I am against Chinese society, Chinese culture, and most of all Chinese people. I have been personally attacked by various people here and quite frankly its quite damaging to see that some folks have a deep hatred of Japanese people when in the reality most Japanese are fascinated with China and what China has to offer (do note that i am referring to people to people processes; politics is not involved). I can count with one hand the Chinese members here in PDF whom I maintain positive rapport with , i used to consider a lot more my 'friends' but recent disagreement have disparaged my view of them. Anyways, i am speaking because I was emotionally affected by the personal insults, i will not rule out possibility of re-establishing with some of them. For the most who are chronic prejudicial , i have added them into my ignore list, even one whom i used to respect the most --- out of all of them.
See you around , buddy. Peace.
