I am both a Linux and a Windows user. I have also over many years examined the nature of prejudice, and it seems to be deeply ingrained in the human condition. Otherwise why would we have these extreme polarizations of human opinion.
These prejudices in most cases are relatively harmless, but then there can be cases where these can be extremely dangerous. Take Hitler who presented rationale for his actions, and even sold this to the general populace and got voting support, so they must have thought his rationale made sense. Here is a sample of the logic: It is OK to dispossess the Jews of their property because that is the LAW. But then who made this law??
You think this insanity is all in the past, then look at todays Islamic LAW and the rights of women. Or even some of todays American LAWs. The way I see it with all the flaming that goes on on the internet, that prejudice and insanity is alive and well. It is that just as long as it is focused on OSes, it may not evolve into road rage, or war, or something more harmful.
