Am I wrong in almost hating that saying, "have a blessed day".

44. Arrogance. Pure arrogance. Have a blessed day.

It assumes that you believe as "I" do. (inclusionary)
  There are many religions in the US. Why should you assume I believe in the same religion as you?
Do you believe like I do?
    It's a way of feeling out the other person. It can start a positive conversation if the other is also
    similar in beliefs. If not, it might be a chance to evangelize. Either way, it's a win.
Arrogance again - even if you don't believe like I do, you should, and you should thank me for sort of
       praying for your blessed day. And I don't understand why you're mad at me for saying that nice
       phrase. Everybody else likes it. (exclusionary)

The response to "have a blessed day" is often a defensive response. I don't like being put on defense. But not responding to it feels even worse.

There is a supermarket near me. Every once in a while there is a new person at the cash register who will say "have a blessed day". I tell them that they are short timers. People at this store who try to evangelize from the cash register don't last there too long.

Sometimes at the same supermarket, if they "have a blessed day" me, I'll stop and look lost, befuddled, confused. I might ask them "where am I?". They might start thinking I'm a little senile. They might say "you're at [name of supermarket]". "Oh, it's a supermaket?! I'm not at church?" "No" they'll say. "Then why are you trying to bring God into the checkout line?"

I really hate the "have a blessed day" phrase. Not just the phrase, but the arrogance (often a naive arrogance) that is behind it.

I've thought about an answer to "Have a blessed day" a lot and I think that I have come up with a novel response to it. It's a unique solution, that so far, it seems, no one else has thought of. If Biden wins in November, I will start the process of putting my answer to "have a blessed day" in motion.

I like living. If Biden doesn't win, my response will always be "and a blessed day to you as well".
