I thought “bless your heart” was just a meme up until I went back to my Midwestern home state with my wife (from Mexico) and our two chihuahuas. In a tourist “town” she’d gone into a bakery and I waited for her with the dogs outside.

Another white family (I’m white) had walked up and started talking to me. They were pretty friendly up until I mentioned we were visiting from Los Angeles at which point they responded “bless your heart” in a heavy southern accent and immediately walked away. It was kind of jarring seeing that kind of behavior after years of living away from there.

I say "you do you" more in the sense that whatever they are doing or going to do is not something I would do. It certainly isn't a "fuck you". It can definitely have some snark like "everything you just said is fucking stupid, but you do you". But the tone is meant to convey that I'm not going to put any further effort into convincing them.

"As per my previous email"

None of those are "fuck you", they're more or less all variants of "I think you're making a mistake". Mixing them up is, well, you do you, and good luck with that.

These are all phrases which are condescending, smug, and emotionally detached.

Saying "fuck you" is not condescending or smug, it's an expression of emotional anger.

Replace any of these phrases with fuck you and the meaning of what you are saying is completely changing.

So I don't agree that this post makes sense. It's straight up incorrect. It's a complete misinterpretation of the English language.

Bold move, Cotton.

I use "good luck with that," when I've been asked advice on a topic I'm knowledgeable in and they decide to go against my advice. It's not "fuck you," but it is "I told you so" in advance.

May your day be as pleasant as you are.

Funnily enough, this works at both ends of the scale.

"Bless your heart" is not only "Fuck you" but "You're the stupidest fuck I've seen all day."

It's very useful, highly recommend.

Only bless your heart can be interpreted as Fuck You but it and all the others are traditionally translated as :

Fucking moron.

I think it's a mistranslation from French.

My favourite alternative to fuck you is jog on.

A colleague kept saying "Love that for you" unironically and genuinely. It lasted a day before someone spoke up about her new thing not working.

After being cut off by some jackass while driving: 👍

"Bless your heart"

"The fuck you just say to me!?"

Where is the 'I love that for you'?

When I have to provide technical support to a true dunce:

"The answer to that question can be found in a cursory examination of the documentation."

When I'm chairing a meeting and one guy just won't shut up:

"Thank you very much for that valuable contribution to the discussion, we will certainly take it under advisement. Now moving on to the next topic."

And here's one that I use when I need to tell a SO/GO/FO:

"Sir, that COA is beyond the scope of implementation for the currently available resources."

Profound

None. There are a lot of shades of gray between 'I love you' and 'I hate you'.
