Continuing with your example of smoking, is smoking not a right of the individual? If we stop people from having the right to smoke, where does this slippery slope stop?
No, not really. Smoking isn't a legally protected right in any country as far as I'm aware; it's just a habit that typically isn't outlawed except in public indoors areas of the UK and I think in cars as well.
Can we ethically stop people from practicing their faith?
Yes, in certain circumstances which I'll explain in the next paragraph.
Isn't that a right that is afforded to all people, no matter where or what faith?
Only as long as the exercise of their right to religious freedom doesn't infringe on other peoples' rights. That's why equality legislation & human rights laws exist; to strike a balance. Otherwise religious freedom would be a trump card to subvert the law like it is in America. For instance, we in the UK don't allow business owners to discriminate in who they offer their services to. An example would be a B&B proprietor preventing a couple from ordering a double-bed room - and thus preventing them from sleeping together because the proprietor's Christian belief that sex outside of marriage is sinful.
I agree that extremists need to be stopped and taken out of the equation but how do you propose to do that? How do you pick those who you think are dangerous and those who are
not, if and unless they openly admit to radicalism?
I don't know. I suspect any such venture would necessarily involve massive State intrusion on our privacy which I don't think is a price worth paying. One or two European nations are talking about repatriating disillusioned Islamic State fighters and they're obviously going to watch them all like hawks.
