This is pure energy and I'm here for it

I wouldn't personally for the same reason I wouldn't wear one of those joke MAGA hats. I would be upset if someone assumed I was a chud.

If that doesn't bother you though I think its harmless. If anyone says anything just say your brother is a vet and he gave it to you.

Stealing Valor is always cool.

Contrary to all the takes here, I think it's a weirdo online leftist thing to do. Funny as a concept though, for sure.

The reality is that you'd probably just look like a dick. A fair number of Vietnam vets were conscripted, and even the ones that weren't are probably pretty traumatized by the experience.

I know, I know, you shouldn't sympathise too much with someone who was very much in the wrong, who might still be a very racist person, but the way to get through to them and to most normal people around you is just to be a normal chill guy.

Also, practically speaking you'd probably get people confronting you about it, judging you, treating you worse, etc etc. Just an all round silly idea.
