My brother is a sociable, extrovert man in his 50s, the life and soul of the party type, full of 'banter', much of it sexist humour (eg a recent meme he shared with me was 'FUN FACT: a majority of archaeologists are women due to their natural ability to dig up the past'.)
He knows I'm a left of centre feminist and as he shares neither of those viewpoints he finds it genuinely amusing to annoy me with this stuff, and the more annoyed I get the more he roars with laughter, he's so delighted with himself that he's provoked me into 'humourless feminist' mode. So over the years I've generally taken to just rolling my eyes or tutting at him rather than reacting.
He's messaging me more than usual, I think in an effort to maintain a line of communication between us, because the sister we both loved greatly has recently died. I want to respond positively because I'm aware that, without my sister to link us, we are likely to drift apart and rarely communicate. However this 'banter' just irritates me and I'm struggling to find a way to handle it gracefully.
There is zero point in telling him it's irritating me as that will just make him laugh, but I don't want to fall out with him either. Can anyone think of a better option than just sending him eyeroll emojis, please?
