I'm sticking to my guns on this one. Had my comment contained personal insults or bad language or negativity, I would agree with you. Try reading that sentence in a standoffish tone with furrowed eyebrows while scoffing at the author. Now read it again in a neutral tone with one eyebrow raised which places no judgement on the person but full judgement on the work itself. I was aiming for the latter.

The bottom line is that these are glaring problems that a five year old could spot and, to most people, it's pretty obvious that if you're presenting something you should proof read it.

Your points in this comment are basically, "I didn't think it was rude so it's not rude" and "I was right so I have the right to be rude."

If you really think those things, I don't really know what to tell you to help you understand what rudeness is.

Similarly, everyone else's points are basically "we think it's rude so it's rude".
