Your sarcasm further proves his point: Leftoids want to use negatively connotated labels like "racist," "sexist," and....drumroll..."bigot" to silence even the POSSIBILITY of rational/logical discussion. In your(there) rhetoric, labelling your argument opponent with one of these somehow means that you win by default; That someone you can stamp with one of these labels can't even add 2+2 anymore, and is therefore not worth the words; That there's absolutely no rationality, no science, no studies, no statistics, that could possibly support any of these bad "isms" and that anyone who subscribes to them (or anyone the leftoid can snap-label as associating with them...which violates two core components of the liberal platform: tolerance and non-judgementalism) has to be so feces-flinging, glass licking insane that they're not even human anymore.
And the disgusting part is: since you now comprise the majority...you have enough cheerleaders in any sufficiently large group that you've internalized this process as sensible and honest.
