Some people want to be the best that they can be and look to forums like these for advice. If they get bad advice, then they aren't working towards what they want.
If your so into letting people decide what they want, then why do you care so much about this? You seem to be taking this rather personal, I haven't done any bashing against you.
Also I do a lot of random pickup stuff and I'd rather have the random people I do things with have a basic understanding of the game mechanics.
Getting false information is never ok, it skews what people will think on things.
