I'm not a native English speaker. Taking care with style, grammar, and proofreading is work. It's work for many native speakers as well.

Also, I didn't accuse them of being sloppy. I said the use of language is sloppy. And I didn't use the word careless, I taking more care would improve the post. One is an accurate description of an action, and the other is a suggestion. Neither is about the OP as a person.
