In Russia, they have only 1 party left, so the party clearly doesn’t matter. In Usa, it is not an official dictator yet. In other countries with a dictatorship, I don’t know about their parties. So do you know any examples where the parties still matter?
I haven’t looked into the details, but it’s more like you can’t criticise the Monarchy, but you can criticise the government, policies and laws. But you can’t incite violence or unrest even online, and cannot demafe government officials. From talking with Thais, this is ok, although they are obviously never too confrotavke speaking openly about it.
