@Delatron I think the US is very diverse. Sure, it's obviously far more unified politically and economically than Europe but in terms of viewpoints and culture, it's poles apart. I lived in urban and suburban NE blue states. I can honestly say, aside from police officers, I never saw a gun and no one I knew had one or wanted one. Abortion was, and still is, accessible and legal. I personally did not know one person who supported Trump, gun rights or was against abortion rights.
I don't live in the US now and personally have a preference for the UK and Europe in general for many reasons but I can honestly say that abortion and gun rights were marginal in making that decision. Access to health care, social benefits and the welfare state, work conditions, infrastructure, food regulations - they were all far more important to me in my day to day life in urban NE coast America . It's not that I don't think gun rights and abortion rights aren't important - they totally are, hugely, and I'm jsut as outraged by what the SCOTUS has done as the next person. But if I were offered an amazing job in the US in the same area that I lived before, I'd definitely consider it and guns/abortion would not really figure in my decision-making as they wouldn't really impact me. Your chances of gun crime if you don't have a gun yourself and live in a state with gun control are really minimal.
But like you said, OP is considering Florida and I'd certainly take pause there. And as for states like Georgia, Tennesse, Mississippi etc - almost certainly not and there I think reproductive rights plus guns would play more of a role if I had to make that decision.
It's just the blanket statements about never moving to the US because of guns or abortion seem totally bizarre and I suspect that it was never actually a realistic option for any of the posters since it's not like you could just up and move to the US anyway!!
