I also often see terms I object to but I do not censor others unless they are advocating violence.
I do object to the term christards however. If they are extreme rightwingers, I think the term christo-fascists would be more appropriate. Even if you think they are more stupid than evil, I find the use of a version of the term retarded to be unpleasant. Luckily the word retarded is being replaced by kinder terms. Indoctrination is unfortunately alive and well among Christians as it is among many other religious and ideologically dogmatic groups.
