One thing that might help it feel less strange is realising that you already use a grammatically plural pronoun to refer to individuals all the time: the word “you”. It’s always “you are tall”, not “you is tall”, same as “we” or “they” instead of “he” or “she”. This is because it was historically plural, and “thou” was the singular. Over time we started using the plural to be more polite, and then eventually always using it.
It only feels strange because of how it’s been used previously in my lifetime, not from historical usage. But as you’ve shown, language changes over time, and not having a singular neutral pronoun has proven to be a big omission in English (since “they” has only traditionally been used that way in certain limited cases). If it was good enough for “you,” it’s good enough for “they!”
“Thou is tall” sounds weird though.

This made my brain short circuit lol. Can’t believe I never noticed.
Yeah but that’s because you see it in archaic contexts. How do you feel about ‘thou art tall’?
No, that’s incorrect.
It’s “Thou are tall” or “Thou art tall”

I’m joining in the “this blew my mind” sentiment and just want to say thanks for sharing this tidbit of info.
