What Alan does not seem to understand is that "identity markers" usually come with certain practices, certain ways of life.
A heavy metal guitar shredder, for instance, probably wants to play loud guitar and listen to Ozzy at high volume.
A Buddhist probably wants quiet time and space to to meditate for long periods frequently.
Now sure, a Buddhist and metal guitarist could find compromises, like the Bhuddist could say: "No playing guitar in your own home."
And maybe certain people would think that is simply asking for a reasonable compromise. But the guitarist might think: "In my own home? This request is an affront to my identity and what I love doing! That is not compromise."
Identity markers aren't just: "I am a _______".
Identity markers mean: "I do ______"
