I totally feel for that, you should not be harassed, demeaned or made to feel bad for that (or anything else for that matter).
But I don't think that the rational answer is to try to convince everybody that your system is more intuitive because the other has "ridiculous" features. I answered to a comment that said: "ridiculously better in the imperial system".
Most people don't seem to care about the units, what the haters care about (not you, but the general experience) is having an opportunity to proclaim how much better they are than other people, mostly over an accident of birth.
