The problem people have with UKIP is that is the 'respectable' face of fascism. Putting fascism into the mainstream and normalising its ideals is dangerous.
Starting off with things like "we shouldn't let people who have gone off to fight IS back in" . Well, you would be hard pressed to find someone who thinks it is a great idea to let people go off to fight for IS and come back to the UK and continue on a racicalised path. So, on face value, the statement is fair enough, right?
But then, you have to explore it more fully.
How do you know who has been to fight IS? You don't. So you have to make educated guesses, so you end up confiscating the passports of people who went to Iraq to see their grandmother or whatever. And it is very time consuming trying to work out people's motives and track them when they are in IS areas.
Also, what are they meant to do with their passport confiscated? Probably go back to IS and become more radicalised and just reenter the UK on fake/stolen passports. Plus with the aided advantage that we have successfully turned some innocent people against the UK.
So we decide to ban travel to IS locations. Fab. Except, well, that doesn't really work because how do we enforce that Exit visas? That doesn't work because we can't control what people do when they get to other countries
So, how about just refusing travel to people who just look a bit Muslim? That would work?
Except, those Muslims are tricky people - they have found ways to leave and reenter the UK (e..g speedboat).
[side issue - this bloody fake/stolen passport problem. What we really need to do is not let anyone in unless they have their DNA registered. So we need to collect the DNA of everyone living in the UK.]
So, now we need to take it another step further? Maybe we shoudl jsut lock up all the Muslims? And also non Muslims who are a threat to the UK's culture like Romanians, Bulgarians etc.
Fuck, we have quite a lot of people in jail now. Conditions are pretty bad. What we really need is a way to get rid of them and reduce numbers?
