I think as with so many things in the last few years, the fault line has been brexit, and there's been so many jokes, from generally wealthier remain voters (comedians, media types etc) aimed at generally poorer brexit voters (the poor overwhelmingly voted leave) labelling them racist, stupid, gullible etc without any attempt to understand things. That has been the greatest mass example of 'punching down' and snobbery I've witnessed in my lifetime. I think it's the double standards really.
This addresses some of it - references Ian Dunt, althouth for me the worse example, the very epitome of smug is James O Brien.

Anywaaaay. I very much advocate a position where we can all make fun of but also respect and try and understand all positions and sharing and experiencing different cultures and jokes is key to that.
