I think the most important thing we can do is continue to try and bring people together by grouping them based on a single feature and then ascribing traits to them, then arguing about it on the internet. We need to keep telling our children to be nice to "black people" and "women are mean to men" and sometimes(honestly a lot of times) "men are mean to women".
We need to start censoring the internet immeadiately and NEVER identify as a diverse difficultly grouped species that cooperates and gets a long.
Now more than ever we need Democrats to hate Republicans, conservatives to hate transexuals and people who use Vim to continue to identify as the gods they are against inferior morons who use Emacs.
also, PCMaster race, if you use linux or microsoft you need to die.
This should be the next X Prize, finding interesting arbitrary (or obvious) distinctions and continuing to allow them to detract from solving real problems.
