Bad grammar/spelling is a minor pet peeve for me too, but I never call anyone out on it unless they ask me to review something for them. It's just rude and unnecessary, especially on the internet where you never know if English is even the person's first language. But sadly, I've known people who were not native English speakers and yet spoke better English than people born and raised speaking only English.
Yeah, basically.
Also when people on purpose ruin your joke just be show themselves off in a better light.. Like okay no that was not what we were asking for.
