Have you considered the possibility that Linux could have been even more successful if it had a more inclusive environment? I can't see how your elitist "filtering" philosophy is necessarily a good thing.

And of course, my comment that is purely based on facts and about professionalism is now all about sentimental and "feelings".

That's why we can never have a productive discussion on this topic.

P.S. looks I hurt some people's feelings by using this Linux example. Maybe you guys are the ones that are most vulnerable and sensitive.
