A little advice about social media from someone who has been on social media since it has existed. You don’t have to argue. When someone wants to argue with you, you should block them. There is no good outcome possible from arguing on social media.
@davew I recently really wanted to ask (in response to an argumentative, off-topic, un-asked for reply) "why did you post that?"
I thought about it for a while, and realised my underlying assumptions were totally unrealistic. I made lunch instead.
