I don't see that we need someone or anyone locking us into a set definition of any words much less kilt. There are too many opinions out there about what is what and how it can or shouldn't be worn for one to be locked into anything. I strongly disagree. Next someone will be correcting our spelling of the various items of wear that go along with being kilted.
And kilt should not be capitalized in any instance unless discussing the proper name of a person, place or thing.
