You tried broaching the subject of nutrition with a vegan? Or health with a Fat activist? Or energy with an environmentalist? Or gender fluidity with... Well anyone... That one always gets a "you can't say that, shhh, someone might hear you" response.

There are plenty of taboo topics. Question is do you know enough about them to debate without emotion in cold hard truths only, without presenting your opinion as fact on an emotionally divisive topic?
