I think so. I think you can judge a bird by their actions and judge people by what they do rather than what they say. There are certain judgments which can be made about a person based on who they 'are' but what constitutes who someone becomes is so manifestly complicated that its pretty much meaningless.

That said, I'm aware human beings behave in patterns and with enough inquisitive questioning you can sometimes get to the root of why a person behaves the way they do - sometimes that's a better indicator of who someone is- asking 'why did they do that'. Identity politics has a simple answer to that question 'because they're an X' - and again I find it somewhat reductive and simplistic a way to view the world.

I understand why people group by identities and inherited characteristics, particularly if they have been marginalised because of them. HOWEVER, I would urge caution, because people who have been marginialised by certain characteristics often share other characteristics with non-marginalised people. It is THIS on which you can create community progress and break down barriers.

My neighbours are liberal jews - the husband is Israeli, the wife is British with an Ashkenazi heritage. That may or may not help you narrow down my postcode. I am not Jewish though I understand this is a reasonably Jewish area because there's another lady across the road who is Jewish too. I'm not plugged into who believes what in my area. :o)
