Some lovely victim blaming on this thread.
I was a middle class child that was picked on at my working class primary (not a particularly deprived area but not posh either). Of course I wasn’t going around thinking I was better than everyone else, at 7 I didn’t have any idea about social class. And being middle class wasn’t about having better stuff than everyone else, it was about having the wrong stuff- the wrong accent, Clothkits clothes instead of what the bullies called ‘fashionable’ clothes, not having local family. One girl would sometimes bring me handmedowns because she felt sorry for me and I was so thrilled to be able to look like everyone else 😂
The teachers loved me and I used to come top in most things which made it worse, I remember one teacher yacking on to the class about how she wished she had a whole class of me because I worked so hard, and I was sitting there mortified thinking ‘please stop’ because even with my limited social skills I knew this would make it worse.
I was friends with the misfits who were also outcasts for whatever reason including proper deprivation, one girl was called fleabag because she was always messy, I think her mum had left, one girl was a victim of childhood sexual abuse though we didn’t know that at the time.
In my 4th year things were better because I and one of the most popular girls in the class passed the 11+ and we became friends.
I will never forget my first day at grammar school, the sheer joy of discovering I fitted in, that I would have friends, that I wasn’t different or wrong.
Anyway guess who got picked on at grammar school, that’s right the popular girl from primary. I didn’t even twig at the time that it was class based because it was nominally about other things that were a proxy for class like her wearing too much makeup or having a perm, but looking back it is perfectly obvious what was going on. We talked about it later and it was clear we had very different memories of school, my perception of my secondary was that there was hardly any bullying, she remembered it as stuck up and snobby. It’s amazingly easy to be oblivious when you’re not the target. (The other person in our class who was picked on was the sole Asian girl so I suspect you can add racist to snobby.)
I am in touch with a few people from primary and generally life has not been kind to the ones who were victims there for reasons of deprivation (my friend who went to grammar school with me switched to college for sixth form and did fine) while yes generally if you’re bullied for talking too posh this is not something that exacerbates existing struggles in the same way. It doesn’t make it ok to dismiss though and the ridiculous idea that if you are bullied for being posh you must have brought it on yourself either by showing off or by being weak and therefore pretty much deserve it just sounds like the sort of thing the bullies would use to justify being vile.
