@BillRM,
No, we don't trust the government which is why it's accountable to parliament. There was no public outcry when these fascists were banned because they're not wanted over here.
Look at the flip side of your argument, you're saying countries should not be able to control their own borders, and that if say a British serial killer released from prison said he wanted to go to America to continue his work you'd have to let him in.
It's nonsense.
Abuses of power by individuals is a separate matter entirely and there are procedures for that.
We don't want these people in our country. It's our country, not yours and you can't tell us what to do.
