I agree that “Keep your identity small” is too general as advice. But the problem Graham has adressed regarding identity is an important one.
So I would propose:
Keep you political identity small. Because as soon as you strongly identify with a specific political group your ability to see reality relatively clearly can be greatly diminished, because politics has opinions about a great amount and variety of topics.
Know your identities and try to realize that you opinions about the world in those areas that are relevant for you identities can be much more biased than in other areas.

Try to have multiple social identities / group memberships because of their protective effects (e.g. Haslam et al., 2008; Iyer et al., 2009).
