Why would you think I'm chastising rather than educating?

You're reading snark where none was intended, and responding in kind.

Double negatives are a problem when you're actually trying to use a single negative which is the case here.

I wasn't offering myself up as an authority on words, I'm pretty bad at both spelling and grammar.

Also, as a Brit living in the US I'm also well aware of different uses of words/spellings and agree that the point of language is communication, and irregardless doesn't cause confusion, as it is obvious what someone means when they use the word.

The whole point of prefacing my comment with, "I hate to be that guy", was to suggest that I'm not actually that guy to soften any perceived insult/criticism.
