The aspects I tire of are the dead horse-beating kind. On the one hand I agree with those who feel that egregious nastiness should not go unchallenged. On the other, having once challenged it, most of us are not going to change our minds nor are we changing anyone else's.   If the first round of challenges doesn't convince us of an error in our thinking - and that does happen- it has happened to me - the second, fifth, or eighteenth round won't either. We are all adults here and we all cherish our beliefs rightly or wrongly.
