No, this is not a genteel forum, as brought to mind with maiden ladies taking their cream teas in a little thatched cottage near railway with an Emmet locomotive puffing away.
We must hope and try to attain a polite environment, which may have to accommodate some rough language as used by the majority of the modern population. There are not always polite synonyms for things which may jar on occasion, and asterisks are a means of avoiding total confrontation with those terms.
It is true that in the first joke I posted, I could have used a different term which would offend no-one. I apologise for that. However, if it became necessary to describe more accurately certain waste, one should not use the c or s word, with or without asterisks, but would you, William, be upset if one was to use in plain speech fecal or excreta . Where do you stop with individual sensitivities.
They say the degree of civilisation goes with distance from, lets say, the sewers. People who have looked after very young children by necessity become desensitised to human waste material, and spend more time nearer the sewers, if you get my drift.
