That was not a condescending comment by my read.

Replace counting in other bases with “theoretical physics” or “woodworking” and it doesn’t read that way either.

I think this xkcd is relevant here: https://xkcd.com/2501/

I was taught how to count in binary in grade 5, is this not a normal thing that kids learn in school?

I think it depends on what curriculum your school's using; non-base-10 math is a punchline in Tom Lehrer's "New Math" [1]. Common Core might be getting rid of it?

As a side note, comparing the complaints in "New Math" (from 1965) to those offered about Common Core is educational :)
