I think everybody has a right to complain. E.g., the recent rich people complaining that their tax rates might become almost as high as their secretaries? They're totally within their legal right to complain.

But I have the legal right to say that they're whiny idiots when they appear unable to notice or acknowledge the context of their complaint. If you're going to cry, "have sympathy for meeeeeee", you really should make sure you've demonstrated some sympathy for others.
