It's an issue of maturity. Our medium and many of its denizens, are immature. I would include myself in that.
Time needs to pass to gain perspective. We will overcome all of these ignorances and immaturities, but it will take time. Our race as a whole has done so in other contexts and I'm confident it will with games. I just hope it won't set us back too far.
I'm hopeful it will not. Hate will not prevail!
