No one is getting 20 years for tweet content in the UK like they are in Saudi Arabia. No grandmother is being arrested for holding up a blank sign like in Russia. I can go on just with the reported stuff from memory for an hour wrt Iran, North Korea and China. I don't even know how many books it would take to read to learn of all the examples worse that aren't.
Look I think there are problems with the UK's policy here, but this comment is either disingenuous or naive.
They may not be arrested for a blank sign, but they are being arrested for holding anti-genocide signs.
