For most of those who are concerned with the wording--I don't see the difference. The object of the employer is the same, as is the end result. Wording it more kindly won't change who he hires, it just means a bunch of people might waste their time applying.

More important is to change the attitudes of the employer--i.e. some non-Lebanese can prepare Lebanese cuisine to a high standard; and some Lebanese happen to be terrible at it.
