We are discussing here the impact of their "no longer" being British politics in Scotland, in your words. That is at best 3 general elections old (we've had 3 in 4 years), evidence for beyond that is fairly scant. So I refute the notion that it is some kind of exception to your rule.
An animal rights activist when directly asked about halal meat can't say he'd ban it because of his Christian love for animals without being called an Islamophobe. If we follow the premise of your argument, 10-20 years ago animal rights activists would be alright with halal meat?
