N) *smiles oddly* Happily, in this international anonymous anarchical Internet, you don't rely on others for survival. All they can do is shun you, blight your name or do other things regarded to communications... but that doesn't matter, because you can seek out others who think the same way as you, and seek to convince others, or be convinced. If you think that someone's behaviour is unreasonable, you can tell them, and tell them why. And if they didn't realise it, then maybe they'll be convinced to change their behaviour, and if there's a flaw in your reasoning maybe you'll be convinced to change your opinions, instead.

In short... there are circumstances in which though others are unreasonable, one won't be able to do anything about it. Happily, this isn't one of them. *smiles*
