Now I say it, it sounds obvious. The instances were:

it's better for the long term if you know what a stereotype is, and maybe even know the common ones, than to not know any stereotypes. With the long term being to live preventing the negative effects of stereotypes, also I think some call this abolishment of stereotypes.

This also goes for other types of social constructs (you might think of one) that people might think are useless or constructed wrong, they don't want to live in blissful ignorance (as i sometimes do), they want to understand the things that could influence their thinking. Now I think about it, blissful ignorance is also way harder to achieve once you know, so this attitude is actually very practical.

Once you know something, to be ignorant about it is just really foolish. But it is possible. I definitely agree with you on this.

sorry, by ignorance I meant actually forgetting about it, or never knowing in the first place, which I say is hard to do, not the other kind of ignorance which I would summarize as maladapting to the information that i have, for example not caring about it. Basically I sometimes think of misinformation or stereotypes or whatever as a cognitohazard, which isn't actually ever helpful.

Gotcha

we need both warriors and worriers

thank you for your service

I like the cut of your jib, mister.

This has similar energy to the idea that one should be offended by other peoples penchant for offence. If the offensive aspects of life are hidden away, one never learns how to deal with them emotionally. Processing emotions is a sign of adult maturity.

Truths:

People die in horrible ways -> There are 8 billion people on the planet -> Crying for every death solves nothing. Proves nothing. -> Work to end the causes of death, not bemoan the death occurring.

Just because your delusion is harmless does not mean that is ceases to be a delusion. -> Even delusional people deserve common courtesy.

Luck, Money, and Agency are all limited resources. -> Hoarding any of these leave less for other people. -> Economies of all of these are cyclic; The more you take, the less you can take, eventually.

Stereotypes don't form in a vacuum; They become stereotypes because enough people lived like that for it to become meme worthy. -> That situation being "their fault" is a completely different discussion.
