You are ruining the image of Atheists!

[Angrboda]

Something that is self-evident doesn't need evidence, faith, or argument to establish its truth. That's what self-evident means. Your suggesting that we need either faith or evidence is tacit admission that it is not self-evident. Moreover, whenever somebody has to point out that something is self-evident, it's usually because it isn't, and they want to undermine the credibility of my skeptical complaints sans providing any actual argument. It's a subtle form of poisoning the well, and is the rhetorical equivalent of your parents saying, "Because I said so."
