Some people are very dogged and single minded when they become involved in a cause and social media makes that very easy to do.
The article doesn't go as far back as to mention the the Twitter GamerGate war years when Graham was similarly deep into activism - the only difference being he was on Twitter's Right Side of History with that one.
A lot of people who criticise him now probably didn't care about his frequency of tweeting when they agreed with him.
I can well imagine the last five years or so have driven him to the brink of sanity and probably into saying things that seem from the outside to be impulsive and ill advised.
It has been uncomfortable sometimes to watch him challenge people for being cowards and sell outs but he's mostly not wrong about those people. It's often the way the message is delivered people don't like (see also KJK).
I think the question to really ponder is how any of us have retained any semblance of sanity? Why hasn't Hadley also completely lost the plot? Arguably we all should have - we should all probably be ranting and raving in the streets because that's how batshit and ludicrous this all is.
The speed and breadth of capture in our governments and orgs worldwide into legislating a pseudo religious stance that basically boils down to men are women, actual women don't exist and sterilising kids is progressive has been utterly, bone chillingly insane.
People worry about a dystopian future but we've actually been living one for at least a decade now. Try and imagine yourself of 10-15 years ago being told that in the not so distant future the Leader of the Labour party will endorse the idea that some women have penises or that the US President thinks it's evil not to give children sex change drugs and surgery.
