Ideological Screed

When every entry in a blog is an Author Tract, preferably all on the same subject.

The author(s) of the blog have an ideology that everything fits into, even if they have to trim off some portion to make it fit. Dissimile, Analogy Backfire, The War On Straw, Easy Evangelism, Insane Troll Logic -- whatever it takes, if it's worth writing about at all, then it's worth preaching about.

Right Wing politics, Left Wing politics, Religion, Conspiracies... The nature of the ideology might differ, but the entries are similar. Many varieties will invite Internet Backdraft, assuming they allow comments from people who aren't of the same ideology. Some of them will contain lots of Glurge.
