On tartans and "entitlement"/"openess" on wearing them:
ALL of the above have a SPECIFIC reason for me to wear them. There are SO many tartans I like that I have ties to, that there is not much reason for me to get ones I don't.

I think of tartans like "team colors" (as I've said before). Each one has its own meaning and associations. To wear it is to associate yourself with what it means. I like the Leatherneck tartan, but as I have no good ties or "reasons" to wear it, I do not out of respect for the USMC and the Marines themselves.
I will NEVER wear a New York Mets or LA Dodgers stuff, because I am a Braves fan and they are the ARCH-ENEMY (one past and one present). In fact, the ONLY New York sports team I will ANYTHING bearing mainly their logo is: New York Knights (from the movie, "The Natural").
Some tartans I would NOT wear either out of respect for what they mean and others BECAUSE of their association.
Other tartans I LIKE/LOVE and want because of their beauty and am glad to have a real, or at the least a reasonable, connection.
Some have a VERY MEANINGFUL symbology to me and I am fortunate that they are also some of the "best looking" tartans of all (Wallace, MacNeil, Carolina, Caledonia) and one that is one of the uglier tartans, but want because of the connection (Wilson).
