I've seen a surprising number of posts on here over time as discussions become heated where the poster dehumanizes individuals or groups, actively or passively, directly or indirectly.
This is harmful to discussion, but more importantly harmful to society and the self.
As such, whether you agree with my assessment of your post or not, I (and others, no doubt) may from time to time point out when I believe a post is dehumanizing. I'll link to this discussion so the tangential argument about whether a particular grouping of words is dehumanizing or not can occur here rather than derailing another thread.

http://www.beyondintractability.org/essay/dehumanization (found via google search, I know nothing about the site, its authors, or biases, but this article appears to make some good points)
This is also a good topic under which to discuss dehumanization in general, or events of dehumanization in society. For instance, calling out a politician, pundit, or other public figure when they dehumanize another person or group.
I do hope everyone takes a moment to understand what it is, its effects, why it's bad, and chooses not to participate in the dehumanization of others, here or elsewhere in your life.
