Sometimes it isn't even media literacy. I've known several nuero divergent people over the years who can have a hard time understanding sarcasm in person unless the person being sarcastic is really over doing it. They have no chance differentiating sarcastic and serious if it's written.

Sarcasm and irony on the Internet are dead though. We live in post-sane times, i cannot ever assume the other person is not completely serious about the utterly deranged and/or idiotic shit they write or say.

I must always assume that yes, that person is in fact as stupid as they seem until proven otherwise/indicated by an /s.

I've read a few accounts of people who've attempted to become completely self-sufficient. Even those with lots of land who spend all their time farming/fishing/hunting find that it's pretty much impossible these days. If you did achieve self-sufficiency at some point, you'd likely only be one failed crop from starving most of the time.

Most of my local ones are registered on https://www.localharvest.org/ (their map seems to be messed up right now, but seems to work if you type in a zipcode, select CSA from the dropdown, and press "GO"). They are more expensive than groceries stores, but don't use heavily exploited labor, and you often get a lot of weird/cool stuff normal grocery stores don't sell.
