These people all seem to have an abundance of TDS receptors in their brains (sic). It's only a theory, but perhaps TDS is a consequence of severe brain shrinkage, which can be fatal in really bad cases.  The body and mind need to have a certain amount of Reality as part of a balanced Ying/Yang. If you deny reality then you create skew towards the dark side, where everything is black. These people not only deny REAL Reality, they make up their own versions. That must be why there are so many crazy people over on the left, who typically get confused about what is in their underwear and can't decide on sitting or standing to pee.
