Yes, it is, and coming back, of course, to life, liberty, and the pursuit of happiness, as the Americans would put it, what's the pursuit of happiness? How do you as an individual citizen follow your dream of what it is to be happy? I would argue that it's to have freedom of conscience, to have freedom of belief or no belief.
For me, as someone who happens to have been very privileged to have been born in the U.K., when I've been in these countries and I've seen that just by accident of birth other people happen to have been born in a country where those freedoms are not available to them, part of what motivates me is that if I believe that for every human being life, liberty, and the pursuit of happiness involve freedom to believe what they choose to believe, then I would want to fight for that right for them as much as I would for my own fellows in the United Kingdom.
