Blocked on Twitter 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 Twitter.

I will debate almost anyone. Stick to ideas and I will debate you. But I do have rules. See Who I block on Twitter.

Twitter is broken, 2016 to 2022: I am on 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 seems to be saved.
