It is a social truism that people tend to want to talk to their current social circle, regardless of topic. Telling people to take it Reddit because it has a subforum for the topic amounts to saying "The reputation and relationships you've spent years building in this community are irrelevant. Go start over with learning the culture etiquette and people over there." It ignores the reality that jumping into a new forum to spout off on a highly controversial topic typically goes south in short order. It isn't generally well received and doesn't generally result in meaty meaningful discussion.
