Do you see how it can be annoying having your opinion countered with "are you okay? you are ready to pounce?"

Imagine somebody replied this to you. You may care, for all I know, but.... why this reply to what is my opinion? Does disagreeing with some line of thinking signify person may be having a bad day? That can come of condescending and preachy. It's something that is not done in usual conversation. You don't assume the person is not well, especially if you don't know them at all, from one statement. It's not like I am interacting with you daily and we can pick each other's vibes.
