I couldn’t care fewer.

[malix@derp ~]$ fewer .bashrc 
bash: fewer: command not found

:(

-bash: fewer: command not found

Your post is fewer than 60 minutes old.

I'm also a non-native speaker and I've also been taught to speak a certain way ("you and I are going" but "he saw you and me"; don't split infinitives; don't end sentences with prepositions, etc.), but then I read Steven Pinker's The Language Instinct and - even more relevant here - The Sense of Style. We've been taught to use language a certain way, but our teachers were following the prescriptivist school of thought. You say these rules were written by native folk, but it's often (if not usually) the native folk that say less when they "should" be saying fewer.

I know you said it's only mildly infuriating to you, but if proper use of language is something dear to your heart (as it is to mine) - I really recommend the above books as I think this is something not worth to get even mildly infuriated about. The border between less and fewer is fuzzier than you think and - in the words of Pinker - once you really master the distinction - that's one fewer thing for you to worry about.

Edit: typo

I couldn't give fewer of a shit

I have used less several times when I should have used more...

when people write should of instead of should have

I've corrected people a few times on this, but then I looked it up, and from what I understand, since language is defined by usage, saying "less" when technically it should be "fewer" is still generally correct. It still sounds alright to me, though oddly the reverse (using "fewer" when it should be "less") sounds fewer (aka less) correct to me.

People thinking the English language is static and has to follow rules.

This Is English, my friend. The top dog of non-proscriptive languages where meanings change over time and reflect current usage.

Want to force everyone to follow the rules?

Start speaking French.

Bash says that the fewer command can't be found...

Sorry, I'll do that fewer.

bash: fewer: command not found

I've tried more instead of less, I will have to try fewer and see how it works, which repo is fewer on?

So what you're saying is we need to use 'less' fewer?

The thing I find interesting is how the mixing of less and fewer, is broadly accepted, whereas nobody tends to use ‘much’ and ‘many’ interchangeably.

I’m not quite sure why much/many is do conserved when fewer/less isn’t.

common usage is not the enemy

Hmmm - maybe I should be using "fewer" less times than I should be using "less" fewer times...

¯\_(ツ)_/¯

Ok so, as a native English speaker, let me inform you, that whatever you think is a rule in English, isn't. It's a guideline. It's a hard language because we lack structure. The native teachers are teaching you the basic guidelines, not actual conversational English, which varies heavily on location, and social group.

If you're able to correct them, you've understood what they're trying to say. So what's the harm?

I refuse to acknowledge anyone's struggle with common words like that except lose and loose.

Unlike less and fewer which are basically interchangeable unless you're being pedantic lose and loose are two completely different words entirely

Less people should be using “less” instead of “fewer”. 😜

Totally agree. I need to bite my tongue when I hear it.

Also see: ‘Very unique’ And ‘jealous’ when they mean ‘envious’.

Same. It's like a tic, I'm compelled to mutter "fewer" in my mind, or else I can't keep paying attention

I'm doing good.
