I've often said "What do we want? Police to face accountability when they commit crimes! What do we actually get? We're going to use the term 'main' instead of 'master' for programming things!"

The other thing is that the big stuff is shored up by all the small stuff.

The reason you can't get police held accountable for crimes, ferinstance, is because there's a hundred shitty racist / sexist / classist / etc attitudes locking down the idea that the police are both besieged by and protecting us from an underclass of people who deserve neither compassion, rights or justice. Look at the people leaping on the 'he was no angel' bandwagon, for god's sake.

If you want to topple the big overt heinous idea, you need to wash away the soil its roots are sunk into and that's banked up round its trunk making it look like an inherent part of the landscape.

A spoonful at a time, if need be. It all helps.
