Blocked on X by the regressive left and Islamists: I love debate. I love ideas. But the Western left and their friends the Islamic right do not return the favour. Their response to opposing ideas, whether expressed politely or robustly, is often to block. See Who blocks me on X.

I like debate. But I do have rules. See Who I block on X.

Twitter is broken, 2016 to 2022: I am on X (formerly Twitter) at markhumphrys. Twitter was a great place for debate before 2016. You could meet everyone in the world, and argue about ideas. Starting in 2016, Twitter became increasingly broken. It became full of reporting and bans and censorship. In 2019, Twitter even started shadowbanning me for no reason that was ever explained, or could be appealed. By 2022, everyone was looking for a better place to debate.

Twitter is saved, 2022: In 2022 Elon Musk bought Twitter and started to end the censorship. It looks great so far. Twitter (renamed to X) seems to be saved.

Campaigns to silence me: I now have no less than two entries on the Banned List at Academics for Academic Freedom. This is a list of "individuals who were banned from speaking at universities in the UK and Ireland, or faced campaigns to silence them, or sack them for their views." The two campaigns to silence me were the BLM protests in 2021 (unsuccessful) and the Israel debate in 2024 (partially successful, in that it drove the debate off campus).
