Starmer was not the PM responsible for making the rules & telling everyone else to follow them
Starmer voted for the rules and restrictions in the House of Commons - Corbyn voted against.
The rules at the time of the "Curry gathering" were different from those at the time of partygate.
The rules for Boris Johnson's birthday and 'beergate' were quite similar - six people could meet outside. Starmer made a performance of posing for socially distanced photos (outside in the cold, wearing a thick coat) the evening before Durham - and then had a cosy beer and curry (inside) the following evening. One rule for Starmer - one rule for everyone else.
Starmer was campaigning at the time which was allowed
Starmer hadn't broken the rules whereas Johnson had
Nevertheless, Starmer didn't follow the guidance for constituency visits - which advised against indoor meetings (they was travelling from place to place) and the sharing of buffet-style food - Starmer said people came in and out of the kitchen to get food (buffet-style).
Dominic Cummings wasn't fined by Durham Police either - and yet he's mentioned up thread.

As I thought - your anger is somewhat enhanced by your political persuasion.
