Or simply the fact that in the normal course of my life I have encountered plenty of racists, neonazis, colonialists, IQ fetishists, wannabe eugenicists etc etc. I considered these ideas already. They all suck and there is no value in further consideration of them, either for me or for our society. These ideas need nothing more from us but to be pushed out of the main stream of intellectual discourse and the people who support and endorse them are offering nothing useful to us by doing it.
