A Breach of Etiquette?

Between the Marines anniversary and Veteran's Day this weekend, I wandered about the blogs and read all the posts and some comments on the topics.
There was a comment by someone on one of the usual blogs I visit that made me stop and momentarily feel ashamed at myself and it's still buggin' me!

I wish I could pull up the exact comment, but I can't find it now in my history. But simply it was a humorous accounting of just what will get your ass kicked for disrespect by any one in the military. It was pretty funny up to the end where they closed by saying that anyone who had never served in the military and used the words Jarhead, Squid, Grunt or any other slang word considered to be a term of endearment amongst those in the armed services would get their ass kicked by a serviceman if used in their presence.

Huh?

I have and I my butt is still unkicked. Is it because I'm female?

I've never used it maliciously. When I was growing up that's the words that were used in my home. Those are phrases my Dad used. I don't think he ever called a Marine a Marine. They were Jarheads. And the Marine Depot downtown was the "jarhead factory". Cute funny names. No harm intended.
Squid is alittle new to me, though. Is that preferable to Swab now? Dad always used swabs or swabbies. So that's what I know.

As for the Coast Guard...I won't even repeat that one! And it was a phrase my Dad never used...I picked that one up from my brother. Now that one is ugly and malicious, no matter how or who says it! That one WILL get a bar brawl started, I would think.

So am I in the wrong? Have I been unknowingly insulting our guys (and gals...note to Pamela!) all these years by invoking those nicknames in conversation and here on this blog? If so, I am truly mortified.
I could cop a pass by saying I am the child of a serviceman. But technically I'm still a civilian. I do feel a kinship, though, by proxy.
If I'm in the wrong here I do sincerely apologize.
