This post is mostly directed at newbies, which aren't supposed to be trained in trying to keep their brain from shutting down whenever the "politics" pattern matcher goes off.

In other words, it could cause some readers to stop reading before they get to the gist of the post. Even at Hacker News, I sometimes see "I stopped reading at this point" posts.

Also, I see zero benefit from mentioning global warming specifically in this post. Even a slight drawback outweigh zero benefit.
