Adult sibling abuse?

[MyTaupeShaker]

We’ve always had a rough relationship. My older sibling (Jo) was favoured growing up so I left home and found my happiness working hard to start a career and settle down with a loving partner. Recently Jo got married and I returned home to help with wedding preparations. The entire time Jo treated me with contempt but I was happy to see other relatives and as it was a special occasion and didn’t rise to any provocations. After the wedding, Jo asked me to drive them somewhere which was an inconvenience to me as I had plans and just weird because other people had offered to chauffeur. I agreed to drive Jo in the end thinking perhaps it was an opportunity to spend a few minutes getting along. Instead, whilst driving, Jo kept critiquing my driving which I ignored and offered Jo to drive the car instead as I was tired from jet lag and wedding prep. Jo then punched me in the face whilst the car was moving and started pulling at my hair. I stopped the vehicle and Jo continued to attack me drawing blood by scratching my arms. I told my parents about what happened but they said Jo was just stressed. My family is south Asian and Jo is the oldest child (33!) They always excuse Jos behaviour. Jo was vicious during our childhood but at this age I feel what happened was really wrong and I don’t know how to explain this to my family. I appreciate all comments and particular anyone from the south Asian community who can relate?

I'm married into a South Asian family and there are a vast many things I will never pretend to understand about how much the eldest siblings seem to get away with but I'm sorry this is just not OK by any one's standards. I'd have left them by the side of the road.
I'd be confronting them and then making a decision which would likely be me cutting ties. Life's too short for that amount of bat craziness!

Assault is assault no matter what sex, culture, nationality or religion the person is. Your sibling attacked you which is a criminal offence. I’d have called the police.
And they’d have been out of the car faster than they could draw breath.

I'm not South Asian, so usually don't understand the whole concept of a favoured child. However, in your circumstances it sounds very much as though, as an elder son, he is certainly favoured and that your parents put less importance upon you as a daughter. Yet, that said, I bet that your parents will expect you to be the one to look after them in their old age. It almost always falls to the women in any family. And therein lies your power.

Quite frankly his behaviour was absolutely inexcusable. You are within your rights to press charges. If your parents attempt to make excuses, you need to be clear that they do not deserve your mutual respect. I appreciate that all parents love their children and don't wish to get involved in their disputes, but if they are actively excusing him and haven't read him the riot act, then i would be distancing myself from the lot of them and under no circumstances would I feel obligated to do any favours for any of them. He can be the one to look after them when they are elderly.

Hi OP, I'm South Asian decent. I can only imagine that your parents have been afraid of Jo so may have appeased them, not necessarily favoured them however it's all the same. Would you have the courage to report it to the police? Even if you drop charges just shit Jo (and your parents) up. This way they will learn not to under estimate you and treat you like shit.

Was Jo with their spouse in the vehicle with you? What has been their reaction? What did you do after the incident? Did you leave with your spouse? Just trying to build a picture of what the immediate aftermath was. Do your best to remain silent until you decide what to do. Let Jo give themselves away

Obviously if you do go to the Police don't tell anyone because they will try to stop you or worse it could escalate

Is Jo male or female? You avoid any pronouns ...
