Why are you asking someone on this site to buy a dictionary? You are at the very least intimidating members' right of free speech lest they fall foul of your imposed rules.
Dictionaries also contain the meaning of words, they are not just consulted for the spelling of words. Since you are a teacher, I must assume you know this, but there again, it's you we're talking about. I sarcastically told Hartley to buy a dictionary because he was being a troll and winding me up. As usual, you ignore the context of the post you refer to, as if I am posting on here in a vacuum. It shows your bad faith and inherent dishonesty.
Let's now just take this opportunity to recap what has developed between us:
You tell me I have upbraided people for spelling errors.
I deny this, and point out that in fact it is you who has done this, if anybody.
You then produce examples in which I have not upbraided people for spelling errors, thus undermining and contradicting your own argument (something you are quite skilled at, fortunately for the rest of us).
Instead of accepting you are wrong, you ask in puzzlement why I am telling another poster to buy a dictionary, showing that you have not bothered to consider the context of the posts you refer to. Or is it because, despite being a teacher, you don't know what a dictionary is used for? Are you just that thick?
Now you say I am intimidating members' right of free speech. What on earth are you talking about? If anybody on here deters speech, it is surely yourself. You seem to treat every disagreement as an opportunity to shame somebody.
Again, you ignore the context of the replies I posted. NewHighlyStrungHartley is now giving us Sermons on the Mount about how we should conduct ourselves as posters. That's hypocritical cant from somebody with years of experience as a troll on this Forum. As explained, at the time my reply to him above was posted, he was coming on here to wind me up. I was initially polite to him, as I was initially with you.
Putting aside the fact that you are plain wrong in every respect - as usual - why are you taking on disputes/arguments I am having with other posters?
Why do you take vicarious offence on behalf of other people, even complete strangers?
