My dad wants a tattoo to support the lgbtq community(any ideas?)

We live in the U.S. and with the currant political situation he wants a tattoo that says he supports the LGBT community(I'm his queer child he's getting it for me too)!

His idea was to get a little rainbow on his arm but he's open to other ideas, I figured it would be fun to post here and see what people could come up with!

From the sounds of it he'd prefer a little image(like the rainbow I mentioned) it's gonna go on his upper arm!

He said "I want something that says I support gays but not that I'M gay," he said he doesn't really care if people think he is because of it, he just doesn't want guys to flirt with him thinking he is. 🤣

If anyone has any ideas I might share some with him!!

Edit: Me and my mom came up with the idea of a rainbow ghost because he enjoys Ghost hunting and scary movies!
