I’ll attempt a little push back to further the discussion.
You’re simply substituting one identity badge for another. Your identity is defined by a beliefs system that reads, “My belief system is superior to yours because I’m able to surround myself with diverse thinkers that challenge my thinking.” You’ve placed yourself in a category, by placing others in the “out” group which you have previously stated to abhor.
You ar playing the same game, and wrapping it up in language that obfuscates what you are doing.
Your tribe may be better for a pluralistic society, but it is still a tribe nonetheless, that has in group and out group members.
