If you look at the image that most Christians show to the world it is one of small minded, very ignorant, intolerant, bigoted, exclusionary, uneducated, inconsiderate, opinionated fools.
Personally, I disagree with this statement. It is the LOUDEST so-called Christians who so show to the world but not, in my opinion, the majority.
It seems the web as a whole and, perhaps in microcosm this site, that seems to bring out the worst sort of Christians disproportionately to their actual numbers. My daughter rarely frequents this site but there are enough examples of the kind of s-m,v i, i, b, e, u, i, o fools that you speak of on sites she does frequent to have her making some very derogatory comments about Christians in general. I have to remind her that her sample may be badly biased.
