Talking about Strawman my god...
I assumed that people are just offended, but are we really talking about immersion here? That is the reason? Being able to see people how you want them to be seen is immersive?
That is just silly.
The immersion thing does not hold water when this game itself has had some wacky crazy NPCS that dress up foolish. People wearing silly stuff into battle fits with the theme of the game.
So the immersion stance holds no water in the context of the game.
