High quality comments are written to convey an idea or present an argument (low quality comments are often written to make the writer feel good about themselves without conveying any meaningful idea). Removing words with high emotional charge but low signal (such as "idiot") will increase the quality and effectiveness of the comment. Others will view the comment more favorably, and any additional discussion is likely to be more productive this way.
