Why YSK?
The first person who typed “should of” probably heard of it in real life that was meant to be “should’ve”, they typed “should of” online and readers thought that it’s grammatically correct to say “should of” which is in fact wrong and it became widespread throughout the years on Reddit.
I hope something could start to change.
I’m not sure what’s misleading. 2+2 != 5 no matter how many “use a grammatical construction” otherwise. That’s like a participation medal.
We call those people ‘wrong’ and we move on.
And, I understand a lot of people can be wrong. Entire belief systems are based on mass delusion, so it’s not like it’d be anything new.
