It sounds personal to you because you are one of those people she was talking about, but she didn't know that. She simply believes that people who think like that are insane, but to be perfectly honest with you Serenity as far as people like her are concerned we probably are insane.
If we are measuring sanity by the standards to which they set it, then we would not pass, because we do not think like they do. However if we are measuring sanity by our standards then they would be the ones that would not pass.
Sanity, like beauty, truth, worth and so very many other things, depends almost entirely upon the perspective and standards of the person who has set themselves up to judge such things.
For all people such as this I always smile to myself and let them rant. They only know things from their point of view, and their point of view is the only one they care about, so even debating with them only gives them more chances to shout about what they believe, without ever listening to another side to the question. You would be wasting your time trying to convince them that they might be wrong, as they cannot concieve of a world where that might be so.
Smile Serenity, no matter what they say OR how loudly they say it, you know the truth about yourself. In the end that's all that matters.
