Jesus, Republicans and NRA banned on school network

This article is important because it shows the unintended consequences of network filtering.

However, the author veers into conspiratard territory when he regurgitates the right-wing victim-hood trope:

Andrew has discovered the issue I write about in my new book, “God Less America.” Public schools have become leftwing indoctrination centers.

This statement is unfounded. I'm sure plenty of lefty, libertarian or non-Republican websites fall under the "political/advocacy group" category. I imagine PETA, LEAP (Law Enforcement Against Prohibition), Democrat campaign web sites, etc would be banned. A dozen right-wing web sites on a ban list containing thousands of entries is not statistically significant. Only a proper analysis can show an actual, demonstrable bias.
