Highjacking aside, I've seen this exact same topic in so many sites (including one of my own). The bottom line is: somewhere, sometimes, someone(s) has to draw the line. Inevitably, there will be those that normally fall close to that line, and Murphy's? Law says they will be on the side they don't want to be. When the owners of a site have their way (and they sould!), a rational person should just take it in stride & go with the flow. OR...I've seen open voting on quite a few sites, and the majority made the rule. This site is set up for polling already, and that could be an easy alternative. It's pretty easy for anyone to ignore, if they object to that kind of posting, and don't most computer systems now have parental language controls??? My system is older, and it still has that to protect the young-uns.
Anyway...my 2c
