I agree on the intersex thing in unsubstantiated, but I still don't understand. Nazis claim that a person's sex should be the one "observed" at birth, legally binding so, end of. Do they fucking anywhere state that this definition excludes intersex conditions? This is the very definition of moving goalposts, and they should eternally stuff it after that, like Rowling did.
(Willie Wonka: Watching conservatives claim there is more to biological sex than genitals at birth, lmao)
Let's not forget that Rowling accuses the "Trans movement" of dehumanizing people, and then goes on to misgender a born woman for her appearance.
(weeps for humanity then laughs hysterically)
[S]ome of you have not understood the books. The Death Eaters claimed, “We have been made to live in secret, and now is our time, and any who stand in our way must be destroyed. If you disagree with us, you must die.” They demonized and dehumanized those who were not like them. I am fighting what I see as a powerful, insidious, misogynistic movement, that has gained huge purchase in very influential areas of society. I do not see this particular movement as either benign or powerless, so I’m afraid I stand with the women who are fighting to be heard against threats of loss of livelihood and threats to their safety.
I hope this asshole regrets this quote now. Fuck Rowling.
You might have a different type of person in mind than other commenters. Most commenters had such people in mind who won't install a password manager or an ad-blocker, or won't hard reboot their Windows unless supervised. Having said that, I don't think that even if you had technical people in mind this fits the question. They tend to take substantial more effort to learn and use effectively than the scope set by the original question. I thought this question was for little things that have a quick, lasting, and substantial effect. Learning awk and sed is a different thing entirely, I think of those more as productivity tools you can invest in mastering, and pay off in the long run.
