Christian memes when made for pure entrainment can bring people together in an excellent way. That the r/dankchristianmemes subreddit for example. It is a fairly well populated subreddit with more than quarter million subscribers. It is unique for atheist and Christian participators in similar numbers. There are few subjects so polarizing as religion online. Reddit having both pro-Christian and pro-atheism pages is a hotbed for debate that often turns nasty yet subreddit is generally immune to this.
