Most of these are not issues that involve science, and that you present them as if they are shows only your own misunderstanding of them.

>More guns create more gun related crime and death, while gun restrictions have reduced them, historically.

More cars create more car related deaths. So too more swimming pools create more swimming pool related deaths. That is not a reason to impose more restrictions on cars or swimming pools.

>Societies with legal safe abortion have better health outcomes for women and longer life expectancies.

Societies with slavery have better health outcomes and longer life expectancies for slave owners. That doesn't make slavery right.

>The big governments of socialist democracies in Scandinavia and Northern Europe report happier people because they are free from worry living in an interdependent society that provides the necessary Healthcare and Education that are bankrupting people here and enable entrepreneurs there.

Ah, so you think other countries should aim for higher levels of ethnic homogeneity, such as Denmark. And cull their population down to 14 people per square kilometer, to match Norway?

And so on.
