YOU have been the only source of either Linux or FreeBSD bashing. We have a pretty pleasing assortment of grownups here, who have gone past the point of needing to claim "my ball is better than your ball". One of my own personal complaints about the Linux groups is that they seem to grow the kind of people who need to disparage in order to feel good. This might be because my only exposure to Linux persons is via Usenet, which is immersed in that teenage-type philosophy. I don't know of any Linux mailing lists of the order of the FreeBSD lists. We don't need that approach here, it doesn't increase knowledge, and only hurts feelings. If you follow up on this thread, please DROP all Linux/FreeBSD comparisons of that order. We all know that both Linux AND FreeBSD are fine unixes, and we don't need bashing here. This list does occaisonally have some comparisons, Linux vs. FreeBSD, but if it isn't kept strictly technical, and non-accusatory, we don't want it or need it. I have seen people in the past that were honestly surprised at the huge difference between Usenet newsgroup rules, and our FreeBSD list rules. If you actually fit in that category, maybe you should "lurk" these lists for a while, so you can see the difference, and not find yourself outside of our lists normal behaviour. > > I came on this list initially to just check was the FreeBSD community > was like, but what I've gotten since is alot of ego and hostility > toward things that aren't completely FreeBSD.

People don't like your need to compare, in order to make one group seem better or worse than another.
