I agree, call other people "网特、共特、没良心的、收了黑钱的、坐在共产党屁股上讲话" is bad. The samething, say other people "Yang Nu, Zou Gou, Fan Hua (Against Chinese People), etc." is equally bad ...
Implying is equally bad as being explicit too.
Instead of attacking people, why can't everybody just attack the point of view.
