Earlier quoted context omitted.
I lost contact with many people because none of them respected me constantly asking to keep in touch outside of facebook - email, for example. I don't have lighter words, even if I consider them friends. Moving on from grammar and culture (in my read, I wasn't offensive, merely stated a fact), what actual solutions, proposals, ideas, can you contribute?
This idea that "merely stating a fact" means you can't be offensive is part of the problem. Your original statement was pretty insulting and offensive, no matter how true you believe it was. If you want to change things, culture is a huge part of achieving that, and being able to express these concerns without being insulting to other people like that is a huge part of it.
They are lazy, that's the sad truth.
