It's not a bug, it's a feature
This legislation, if passed, will drastically reduce the availability of internet access in Alabama. And that's a feature, not a bug.
Internet access means that your average undereducated Alabaman may stumble across websites causing him/her to question many things: Are Republican politicians corrupt, greedy bastards who steal from the poor to give to the rich? Is Donald Trump sane? Was it a good idea to marry my sister? Are black people really inferior? Is there really a God?
Jack Williams' career, and the careers of many politicians and Talibangelicals, depends upon people NOT questioning those things. So he wants to put Alabamans in a bubble and justifies it by saying he's protecting them.
