Actually, PC users started it. All of the Mac users I've see are innocent people and then there's the PC fanboys always [first to] pick on Mac users and how they suck. I haven't heard one good reason about why Macs suck from any PC fanboy. Oh and saying Macs suck because it just does is not a reason at all, much less a good one.
I don't hate PCs generally, but seeing extreme [PC] fanboys being really biased kind of pisses me off. My friend who has an Alienware computer boasted how his 6K gaming machine can beat a Mac Mini and how [Alienware] supposedly cheaper... (???)
The vast majority of Windows fanboys have a love affair with Windows simply because of gaming. If Mac OS X could run all PC games natively, I bet 99% of them would rush out and buy Mac Pros. Don't believe that? Seeing as how so many of them are uniformed and plain ignorant, it wouldn't surprise me at all.
I just got into it with a Windows fanboy the other day when he said that Macs are simply ego purchases to make their owners feel better about themselves. I replied "Yeah, sure, so why did you spend $1,500 putting a gigantic sound system in your car? Why did you spend another $1,000 on your car's tarted-up paint job? Wouldn't have ANYTHING TO DO with you wanting other people to NOTICE and think you were COOL, now would it?" (He had nothing to say to that.)
But ignorance is the key. Only a Windows fanboy would be able to rationalize in his own mind a contest between a Mac mini and a quad-core Alienware. Oftentimes, Windows fanboys don't know anything about the PPC-Intel switch or what processors Macs even use.
One of my coworkers, a guy in his mid-30's whom I've decided to dub "The AidenShaw of Walmart" is a know-it-all Windows smartass who gets snotty whenever a customer asks him if a particular peripheral is Mac-compatible. He'll say something like, "It might work, but Macs aren't compatible with anything so it wouldn't surprise me if it's not." I asked him why he said that and he replied, "Macs suck! My dad is in love with them but I've always hated them. It used to piss me off back when I was in high school that he spent so much money on a Macintosh when you could get an IBM PC for less. I mean the only thing more expensive than a Mac then was a Silicon Graphics workstation for like $12,000. But yeah, the Macs can't be upgraded or anything. Every time they change the operating system you have to buy another computer. If you want a bigger hard drive or more RAM you have to send them to Apple. And if something breaks then you're screwed. They're retarded."
So really, it just boils down to the fact that people like running their mouths more than checking facts.
