Sure, and I agree with the suggestion. It's just not very effective to be hostile and vague toward people when you're trying to get them to change their habits.
(and my previous comment intentionally committed the same mistake)
Either give objective change requests or try to explain your point. ("your" as in an arbitrary reader, not you jgwil2)
While we are typing English, many places still do not mind using a default gender in their native tongue, and a non-native speaker can end up writing like that when writing in English. Heck, even English (the language) natives haven't fully settled in using "they" or which of the other variations the grand-uncle to this post mentioned.
I have no clue about the original poster's nationality, but I consider it rude to presume people are using this kind of language maliciously, especially on the Internet where you can't know what is acceptable in someone's culture.
