I'm okay with a country jailing people for the crime of tweeting "we should murder all trans people". That probably should be a crime. Punishment should fit the crime though, so no more than a few weeks.
What about when they jail people for tweeting about how they don't want more immigrants?
Literally never happened. You just are way too online if you believe that. Try visiting the UK sometime, you clearly never been and it’s a great country.
