I don't think Vance was making an anti-abortion point, it was part of a broader theme of the free speech clampdown in the UK, he even said 'we may not agree with you but will defend your right to say it', or in the UK's case, even think it!
Hopefully it's a wake-up call for Europe. The question for the US is why should they spend billions guaranteeing Europe's security if our shared values are no longer there. Reading West Didsblue's posts, they would be extreme even for the 1950's Soviet Union that NATO was formed to defend. Why should the US pay for the protection of people like him when US taxpayers would much rather have that money spent at home?
