I don't wish to insult anyone.  But I will say that I have tried to 
learn linux several times and found poor support from the linux 
community.  Mostly I think there is an attitude that "we" (the linux 
community) got it *right*, when there are many, many more PC users, even 
professional programmers, than there are working under Linux.

Ok, everyone is entitled to their opinion.  But the problem arises when 
it is not understood that this is an opinion, not a universal truth. 
There are good and bad things about both linux and windows.  I would 
like to learn about linux now, so I won't ask "why" anymore.  I'll just 
accept the things that are goofy about it just as I have done with 
windows for many years.
