Why the division?

Its pretty late in California right now. 1:30A.M., I'm doing my late night web runs (Since I've been jobless for the last 2 weeks what else is there to do?) and one question pops into my head.
Why is it that we are divide as a nation? Looking back through the glass of time, I can remember NES vs. Master system, SNES vs Genesis, Saturn Vs Playstation VS N64, Dreamcast vs........ so on and so on.

But going through my 25+ years of gaming I can't remember ever arguing about system A is way better than that system B because....of games?.....Graphics?, nope! today's points are based solely on sales and the money generated by said system and said games on system. WHAAAAAAAAAT! I know at this point its like digging up a dead horse just to add a few more bullets to the poor animals skull but why are we as a nation so divided by something that is so separate from us to begin with.

If this game sells a billion and this game only sells a few hundred thousand, why does it matter so much? I mean we aren't seeing any of this money and its quite the opposite, we actually make these games the successes that they are buy giving up our money and yet we will argue to the point of being racist, ignorant jerks to prove why we bothered to make this game a billion dollar success and call those who did not put in things that will make our forefathers spin in their grave. Why has this happen to us? I remember growing up with Nintendo a good friend of mine was all about Sega, we still interacted like normal, played together and when it came down to our videogames we asked, what are we playing that day? Are we going to my house or your house? That trend pretty much continued up until X360 released. All of a sudden if you weren't online with a 360 we couldn't be friends in real life?!?!? WHAAAAAATTTTT! Then the PS3 released and if you owned one you just threw away $600 because as far as "Gamers" were considered it was D.O.A.. What happen to us? we used to share our experiences as a people, used to talk about games that we could play that our friends couldn't and vice-versa. But now it seems that system ownership is a lot stricter than religion. "Buy what I have so we can talk about it or F*** YOU!!" Why and How?

I'll admit early on I was just as rabid as the next person but I've been able to let that go, but it seems the problem has only gotten worst and not better, despite there being many ways to enjoy our freetime, it seems that you can only have one way to enjoy it or else you're an outcast. Sad really but I guess thats the way the world is going.

P.S. This was just a random thought but feel free to comment if you like.
