If you know who he is you’re either a fan or think he was a thorn in the side of small-minded and religious folk. Maybe both.
If you don’t know who he is and want to learn more about him; there’s a lot out there written by him and also a lot written about him. I don’t think there’s much more I can add in the 300ish words I usually write.
Besides his writing, Hitchens was a well known and enthusiastic debater and he seemed especially fond of taking on religious speakers. Most videos of his debates or panel discussions are at the least entertaining.
As far as I know, he held on to atheism throughout his fight with cancer and to the end as well. Good for him. I’ll miss him.
