How do you deal with arrogance?

[NeverGotMyPuppy]

I met a woman about a year and a half ago. We get on and have DC the same age.

But she is unbelievably arrogant. She has just messaged me saying she has had an experience of the job I do and asked if it was normal for everyone to be crap etc etc, completely slating my profession. She didnt once have the awareness to say 'I'm sure you arent bad!'

I'm just sat here agog at the arrogance. It's got a lot worse recently. Do I assume its insecurity and just continue and say nothing? Do I just quietly leave the friendship? Call her out?

I'd reply with, "Your experience sounds very different than mine. Thanks for the message, though.", and leave it at that.
I deal with face-to-face arrogance with a half-smile and a mental middle finger.

That's better than what I sent!

I tend to either be blatantly rude or sarcastic, or be as arrogant in return. So my reply would have been along the lines of 'oh, of course not, anymore than all (insert friends profession) are all massive wankers'

Preferably tailoring massive wankers to the most unflattering stereotype of whatever it is she does.

The best revenge is when they walk themselves into a scenario where you've done/ are better, but keep it to yourself until the occasion is relevant.

I don’t think that’s arrogance, I think it’s someone too thick to realise how insulting they’re being. Probably if you said ‘Seriously? Are you aware I’m an X?’ she’d say ‘Oh, I didn’t mean you...’ just like a certain kind of racist slags off Asians/Poles/whoever to their Asian/Polish colleague, and thinks they’re actually paying them a compliment by doing so, because it implies they’re somehow acceptable...
