I find it depressing that not wanting migrants to drown, is framed as 'support for migrants' and somehow left wing.
If a suspected rapist was drowning in a pond, I'd expect the police to save them, then jail them. Leaving people to die without any right to a trial or to be heard, is simply sociopathic.
It's perfectly possible to have a hardline anti-migration policy, which doesn't involve allowing thousands of people to drown.
