The UK is at war with radical Islam. They do not have to allow enemy sympathizers freedom of movement within their country. I’m sorry you don’t take the threat seriously.
The US is at war with radicalism, too, and we saw how well American’s rightwing responded to Homeland Security’s even mentioning the possibility of problems.
The UK may not have the US’ constitutional freedoms, but they’re not about to imprison or deport thousands of people based on, “We think you’re thinking illegal stuff.”
