Yes he did, but thankfully he has recovered now
. I don't want to say X is completely at fault and point fingers, but he put out a verbal statement on his website (
https://richarddawkins.net/2016/02/an-update-on-richards-condition-in-his-own-words/), which was very interesting. He refers to events preceding his stroke which is key.
He put out a very witty video (which he later took down after backlash) on his twitter. The video was basically comparing feminists to Islamists (check it out on Sargon of Akkad's YouTube channel: "Feminists love Islamists"
. This triggered a lot of offended feminists and "social justice warriors". Dawkins faced a huge backlash, and got dis-invited ("de-platformed"
from an atheist convention (Ironically a "skeptics" society). The worst thing was he faced a lot of abuse and, shall we say, harassment on Twitter which was the same, if not worse, as the stuff he gets from religious people. He said in that statement that this may have put him under a lot of stress and pressure and was a factor to his stroke. Basically, it was horrible treatment of a renowned atheist figure (not too dis-similar to how Sir Tim Hunt was treated) by other atheists and liberal-minded people.
This whole debacle shows how much of a cancer "atheism +" has become as someone mentioned before.
This was a brief account, I may have missed some details. Sargon of Akkad covers this more if you are interested.
