This is the most sensible thing I've read. I agree with this: if you don't like the content and don't know what to say, don't leave anything. Just vote and that's it. It's better than saying something stupid. Your comments are very organic, for the most part. But as you say, now there are people like this everywhere and they cause a lot of trouble. You want to be cordial, but they're really not being honest and they're committing abuse.
