Is it considered disgraceful if I have a Marine Corps flag hung in my room if I was never a Marine?

I served in the Navy as a Corpsman in a Marine battalion on Green side and then transferred over to Blue side, to later work on a ship. In my room, there is a Marine and Navy flag hung on the wall. What do you think? In all honesty, I hang up the flag in my wall because I love the anchor/globe insignia and the red background.
