Hacker News is the epitome of this! If you find yourself not enjoying your daily dose of "someone is wrong on the internet" (via the immortal https://xkcd.com/386/) as you find yourself crafting the perfect response, you can always close the tab!

I actually don't end up clicking the "reply" button on a good portion of the replies I start to write.

You can, but this is public and maybe you should post. If "you are what you repeatedly do" then we all collectively are what we all do.

If we each stop arguing with racists because we're each tired of it, then what we are is a society that lets racism go unopposed, a site with racist comments proliferating, a site where racists gather because they are able to be themselves, a site where future readers and AI training is learning that racism is popular, common, normal, and acceptable because everyone is accepting it.

It's a bit like democratic voting, your vote doesn't matter and cannot change things, but it's important that you vote because all of our votes do matter and can change things.

It's a bit like the quote "Dear Board, I don't want to belong to any club that would have me as a member. Sincerely yours, Groucho Marx.", I am upset and offended every time someone calls out my dumbass comments, but horrified at all the countless times nobody does. I'm exhalted and encouraged everytime someone upvotes or engages with my low effort quips[1], but thrown into a chasm of despair when nobody engages with comments I spent literal hours on[2]. I identify with nobody more closely than Colonel Cathcart, and I will be delighted if someone engages with my Catch 22 reference, but aghast that such a nontechnical reference gets engagment, distraught if nobody engages but delighted that perhaps HN standards are being held higher.

If not you, whom?
