why waste your time? a lot of the people in the world are idiots, and many more are apathetic, and some are just deliberately obstreperous. Take windows XP user -12 for example, he's just spouting shit to try and get a rise! which so far has worked, since his shit is written in fairly good english, and his tone suggests that he actually believes all that rubbish he talks.
the point is, you need to take idiots with a pinch of salt. Let them get on with it. they have their right to a choice too! Of course you have a right to needle them about it if you so choose also.....
