For me, "you do you" is always sarcastic, and "do you for you" is always genuine. Kind of like when someone asks me how I'm doing "I'm doing good!" Is genuine, "I'm doing well!" Is a lie.
I think this personally depends on the context. For example “you go to school and you do you” this can be seen as encouraging. However “you know what, just you do you” this is argumentative so I think it depends on context.
I can't say I've ever been sarcastic when saying that. Dismissive: sure; but not sarcastic
Dismissive?
I frequently do so it's factual at least.
No. But you do you
What does 'you do you' mean?

It doesn't have to be at all.
