We have a number of people on this site, like Captain_Feelgood, who persist in attacking people with whom they disagree by simply attacking the person, not the topic of disagreement or the behavior shown. That is despicable, uncivil, and immoral behavior.
I believe that we of the Atheist. community owe it to each other to let those people know -- each time they act in such a manner -- that we do not accept or conduce such behavior. They need ty hear it from as many members of the community as possible.
Certainly some content on this site is ennobling, but it is mostly entertainment. One can either allow themselves to be abused by others or block them. That's a choice you can make. (It is bad form, so at least it should be done artfully?).
My art, crude though it is, is to ignore them. They seem not to have noticed this.
