I equally strongly reject people who cloak racism in "science" that is full of holes. Just as strongly as I object when someone justifies silencing others based on personal offense. You proceed down that path and there's no limit to that reasoning. And I hold both sides equally to that logic. What I warn people against is the insidious slippery slope of people (from either side) who gain (or assert) power to police what people say, and gradually turn the knob from (for example): fighting racist policies to the much fuzzier and dangerous I-am-offended sensibility that targets anyone who wants to talk about something reasonably as racist/sexist/xenophobic. The parent comment strikes me as that vein.
