Claiming something is easy to do and then making the same errors simply diminished the strength of the argument presented. The comment comes across as "do as I say, not do as I do."

it's fun for text-based debate, but aren't you just ignoring the greater contextual situation for the sake of argument? the distance between anonymous internet comments and professional discourse is wider than what you're implying

Why should the distance between between anonymous internet comments and professional discourse be wide? If your comment is about professional matters then you should have enough professionalism to make you point appropriately.

i mean, from my understanding of the english language, these kinds of things are usually contextual based on the medium, not the content of the message. i suppose everyone has their different interpretations, though

I'm focusing on spelling, not grammar (I consciously exclude grammar from my heuristic, out of respect for non-native English speakers). Are there any misspellings in the OP?

Your use of the term "typos" includes all typographical mistakes, spelling, punctuation, etc.

You don't appear to have spelt any of the words incorrectly. However, you did make a couple of typographical errors. A close look will show them up.

In regards to spelling errors, do you distinguish between the American and the more correct non-American spelling of words?
