I think one reason why liberals use social media so effectively is that conservatives have jobs. I have a Facebook account that I created primarily as a business development tool, and I rarely use it. I simply do not have time to read through and respond to everything my Facebook "Friends" (some of whom would not have given me the time of day back when I knew them in person) posted, I would not have time to do my clients' work. I am therefore on Facebook once every few months. Some of my liberal friends post multiple times daily.
I do think what happened to this student requires a very strong response, preferably through the legal system, as well as with some significant and bad publicity. If we do not shut down this nonsense now, it will only get worse.
