Umm... last time I checked, I admit it has been a while, pretty much the same is possible in Windows.
This is how flamewars begin. If you are really talking about the problem being users (which I agree with) then you need to keep it general and you do not need to reference ANY operating systems.
As for the racist bit, if you read the line to the end you'd have noticed the reason why it doesn't matter. Please do so next time and save me the need to point out the obvious.
I did not call you a racist, I only implied you were not being truthful. You need to learn how to parse what you read better.
As far as the truth, you keep referring to individual operating systems when it sounds like you are trying to say they don't really matter. If they don't really matter then why do you keep mentioning them?
In order to get your ideas across better you need to improve your English writing skills (i.e., don't say stupid shit like you are not trying to start a flamewar). If you are not trying to start a flamewar then it should go without saying (i.e., it should be "obvious").
And yes, the operating system does matter. You are only looking at Linux usage on the desktop, how many servers run Linux? If you add them into the total Linux usage then then the "market" is pretty big. Linux servers can get compromised too, in fact the only Linux boxes running AV these days tend to be servers.
Anecdotally none of the friends who I set up with Linux (and NO antivirus) for surfing porn have gotten owned, so I would say contrary to your assertion the OS you run DOES matter.
