"I wouldn't say "liberals" are in a minority in the UK"

Hmmmm. Economic liberals aren't, more's the pity. Perhaps social liberals aren't, but that's not reflected by the rise of the right in the UK (kippers and tories) or it's consequences (Brexit) so I think they are.

Perhaps I should have said "progressive, free-thinking individuals who value compassion, curiosity intellectualism, culture and diversity" might be better. As that's a mouthful, we'll call them "Progressives".
