Donny's rants are of course a whole load of crap, but he does not do the "trans being insane" or most other weird rants, to convince normal people about it or to tell the truth or even pretend to tell the truth. What he does is, he affirms the views of the people that provide the base for his (well) popularity - the people that already are leaning that way and that are, for lack of a better word, gullible into accepting those rants as something to believe in.
