Keep Your Identity Small  
I think I concur that in educated discussions Identity does not help, but I have been thinking through the importance of identity for a while.I think in many situations identity gives you strength. I have an identity within Y Combinator, with my family, with people that went to my University, in the countries I have lived in etc. These fragments of my identity all give me strength, it means I would help people out that have similar identity to me and I know people in those groups would help me. Beyond aid, it also give me purpose and meaning.This balance between the good and the part parts of having Identity are important. I don't think one should just try to blindly minimize identity. Maybe just try to keep an open mind in discussions about Identity.
