Britain has extended tolerance to religious dissenters for over three centuries - e.g. the Toleration Act of 1689 - but always on terms designed to maintain peace and national sovereignty.
Perhaps the regulation of religion needs to be brought up-to-date, and maybe the model should be changed. Everything is commoditised these days, so why not treat emotional investments in chosen philosophies like financial ones?
For example, after a rant against the infidel and a call to slaughter him, for which the promised return is an eternity of brilliant food and sex in Heaven, firebrand preachers should add, "Regulatory warning: souls can go down as well as up."
