OK, so I googled – he is accused of various crimes, nearly all to do with saying things. Some of them amount to incitement to murder and to rise up and take arms, which are illegal in an ordinary mainstream sense without specialist terrorism legislation. So – if they were true then he would be tried and convicted of those crimes. But he isn’t?
I find that the very people who are in favour of summarily imprisoning or even of just murdering him are the same ones who have the least idea about what he is accused of. Which basically means they are racists who want to kill bearded foreigners because they don’t see them as being as human as everyone else.
