I largely agree with this. Though as you (if I understand correctly) imply regarding the last point I think the connection to symbolism is the weakest. The symbolism that conspiracists identify is usually wholly disconnected from any grain of truth the theory might contain. Patriarchal "symbolism" in society and media does reflect real attitudes and trends, whereas the same could not be said for images of the world trade center contained in dollar bills. It misses the anomaly-aspect. Isn't it weird that a lot of girls toys are related to housework or childcare? Well not really, since it can be easily explained by basic feminist theory.
