Were murdered dissidents "perfectly able to take care of themselves"? I believe they could have used some help. I'm not sure how to effectively help them short of starting WW III, but speaking against China's policies and refusing to help the Chinese government is a start. Call that "China bashing" if you will but in America "bashing" government is an honored tradition.
