It's illegal to honk out of rage (at least in California). I'd know, my sister's gotten many tickets for it.
I suppose my inner rage is one for people who feel like they have to try so hard to prove something that they argue over the stupidest shit, or pretend like their opinion is above fact. Taking objective matters and pretending the matter is subjective and that their opinion is just as right as factual proof. i.e. when my little sister was 15 (!!), she used to say that frogs weren't animals, because she didn't think they should be. She would insist she was right, because "it's all just opinion anyways."
Then there are people who try to take a subjective matter and pretend that their subjective point of view is somehow objective and "correct."
I rage deep inside but I vent alone.
