If you think about it, this site is like a sieve. Over a fairly short period of time some of the nutcases become evident and then it's just a matter of filtering these posters out of the equation, i.e. if you don't mind they don't matter.
No need to mention names. If we all agreed all the time we'd have to find something else to do (or the wife/partner would find it for us!).
I'm sure most folks on this site have put something they wish they could retract but that's ok. It's the ones' that do it all the time that just need to be ignored. Eventually they'll find someone else to bore (once they've run out of people in the pub to impress).
