Zeebra, its each to their own. There are certain people who'll never listen or repeatedly ask the same question although it was answered - such a Bmag, Vinny, and so if you recognise them its best to never post in reply to them - and so never fuelling their ignorance/stupidity then they go away. Or throw them a curve-ball (i.e. tongue in cheek bullshit).... but one thing for sure, don't let it get to you.
