I'm curious, whcih Linux forums did you visit, Zombie? The ones I've visited, the members, with few exceptions, were generally polite and very helpful.
I still think there's a place for proprietary software, and there's benefits for it. But there are also benefits to open-source and/or free software as well. They can co-exist peacefully, and even help each other out indirectly by both of them striving to improve and make the best product possible.
