I have a cousin who is adopted. He is as much a part of our family as any of the rest of us.

Would it be considered inappropriate for him to wear our tartan?
Would he be as "entitled" (whatever that means--waves hand in a passé manner) to wear the colours that represent his adopted family that reared him from very young childhood?

I understand that "clan" means "family," often a group unconnected by blood but rather by geography and symbiosis.

I don't mean to start a thread with any controversy. I know that this could be a very emotional thread. Let's keep it cool.

Thank you.
