[You must be registered and logged in to see this link.]It is an article about how the Internet influenced the way Dylann Roof became more and more racist.
I think it is an issue most people know and yet it is not talked about that much. The more you search on Google the more Google knows and understands you and so it enables him to show you websites that you are likely to like first. It is thus more difficult to read different opinions from ours and it reinforced our first thoughts. For example I have read somewhere that a pro-life user who google "abortion" would probably first find religious websites against abortion, whereas a pro-choice would find links to websites by private hospitals who abort women.
