I have never read anything written by 'Qanon', be that a person or a group of whatever it is. Most Americans have not. But politicians sure seem bound and determined to criminalize it. Lots of people say lots of stuff on the internet. Nobody cares and certainly not politicians. Their bipartisan attacks on Qanon smack of something like anger or fear and tells me he's striking a nerve.
In other words, methinks the Senators doth protest too much.
