That was one of my thoughts when Khan gave his speech at the DNC. We have many examples of otherwise non-public figures temporarily entering the public stage and inviting the full
flying monkey attack. People who don't dwell among the rabid lambs of the internet and talk radio might not be aware of what it can and does release sometimes. I do hope someone in the Clinton/DNC teams sat them down and informed them what they were getting into. I also hope there's a willingness to provide financial and legal support if necessary.
