Example of a jerk trying to justify his anonymous down -voting
http://math.stackexchange.com/users/147263/raff:
For a Mathematician, Raff -- or whatever he changes it to -- is very fond
of fallacies, one of them being the false dichotomy: we must serially downvote
lest the place become unusable. No evidence of this is ever offered. Raff has never
answered. Common, Raff ( or whatever you change it to ) convince me you are not
engaging in false dichotomy. Maybe instead of spending so much time downvoting you
could come up with creative ways of teaching people that do not involve the cruelty
you so seem to enjoy.
