Well, firstly, being pro-life but an atheist are not mutually exclusive. Some on the religious right tend to quote scripture or religion in their arguments, but you can simply believe that life should only end of natural causes. There is no greater act of hypocrisy than that of the orange haired idiot who was in the White House between 2017 and 2021, who proclaimed that he was the number one defender of the rights of unborn children yet he approved the state-sanctioned murder of an intellectually disabled woman on death row! I say, though, you have to be consistently pro-life, you can't be anti-abortion and anti-euthanasia but pro-death penalty. You can, however, say, "Okay, I don't support the death penalty, typically, but I'd make an exception in the case of say, Ted Bundy." Or, say that you found televising Timothy McVeigh's execution barbaric (which it was).
Similarly, you can be pro-gun but pro-environment. My stance on guns is this, and it shows how misinformation can be counteracted. My Year Five Teacher was a radical animal liberationist, who told us to tell our mothers not to give us meat, and where to get free range eggs, and she wanted us to message politicians to call on them to ban shooting animals. My father said to me, "The men who shoot brumbies, donkeys and other wild animals, are expert shooters who've had years and years of training. And there's a difference between killing and culling." I don't support some drunken yahoo with a gun who ends up shooting at empty beer cans on tree stumps, and I say, in countries like Australia, farmers should be told, "Right, you can CULL kangaroos, but you MUST NOT EXCEED your quota." Nor do I support the right of rednecks to say, "No lawman's gonna deprive me of my Constitutional right!" I believe that, the military and the police should have weapons, naturally, and qualified, certified hunters, and if you are a sporting shooter, you should be able to go to the rifle range for target practice or competition, BUT, you shouldn't need to take your gun home and sleep with it under your bed. And, I think it is IDIOTIC of a president to say that teachers should be armed!
You talk about being half-red and half-blue and I'd like to give an example of an American who went to live in Australia. His parents bought a Ford Falcon when he went to live in Australia, and they had a Chevrolet Camaro shipped over from America, and they kept the two together. You can't exactly ask a person which they liked better a Camaro or a Falcon, as they're completely different.
