The NYTimes is all excited about the findings of a group of Swedish researchers. In a number of different sections of of the times, based on my RSS feeds, they posted an article in which homosexual men responded to a pair of chemicals thought to be pheromones the way normal women do, not the way normal men do.[1] The researchers claim that the data on homosexual women is "too complicated" to publish, which leads me to question this study, how and why could it possibly be "too complicated?" Further, they admit that they cannot, from this study, tell the difference between cause and effect. Which means that they do not know if homosexuality is causing the changed reaction, or if the changed reaction is causing homosexuality. Either way, this does not detract from the idea that homosexuality is, at root, a disease, it just means that it may be a physical disease and not just a mental one.
