Dear me, I'll try to explain in plainer English.
The post directly above is a childish jab that has nothing to do with the conversation. It demonstrates an attitude that is not conducive to discussing race relations or anything else of import. If you want to be seen as an intelligent individual capable of adding something valuable to the dialogue, it would help not to post things like this.
The posts that people made that characterized a certain race as to having certain negative traits on the basis of their race alone were taken to task, as those posts could be considered racist by it's definition. If you don't want to be called racist, don't post racist things. If you want to be considered intelligent, post something that can be considered so. Not sure where the scum part came in but fair enough, if that is how you feel. Again, not all posters are being called racist, but several posters have said some very borderline things, and some have crossed the line. It may not offend you personally or match your personal definition of what racism is, but that is a different issue.
I called out 47MartialMan because he posted some things that were unacceptable. You admitted to not having read his posts. As such, you don't have any basis to comment on my posts concerning his if you haven't taken the time and effort to read.
I hope that clarifies things for you a bit. No need to be timid, say what's on your mind. Just don't be childish, racist, or unintelligent and you won't be labelled as such(at least by myself).
