I think this is a tempest in a teapot. The "hugs, kisses, sweetie, and smooches" are just our inane way of trying to sound feminine in dumb way. If you know the person that you are talking to well enough to use those terms great. I've done that and signed off using hugs or kisses to friends. If used here for all of us....maybe not right, but we aren't exactly the social norm anyway.
