For many reasons I’m not on Facebook or X (I mean if you’re still on there after Musk started doing Nazi salutes then you’re never coming off).
But one of the reasons is that you are sharing a social space with literally every person who’s got sufficient reading ability and a smart phone to create a login. If once you’re on there and someone whose views you disagree with starts disagreeing with you or being threatening or aggressive then you need a thick enough skin to take it or don’t go on there in the first place.
Personally I wouldn’t cope so I keep out in the same way there might be certain pubs I wouldn’t go in.
Gareth does his videos and uses X and Facebook to promote them so he’s sailing his boat on the Cess Pit Sea and can’t be surprised if a few sharks jump out when he makes a mistake.
