Since you have said that you don't vote, maybe you should just sit out discussions of how other people vote, especially if you are going to be judgmental about how they vote. If you are just going to sit on the porch, maybe just keep your discussing on the porch.
I can't because I am Christian.
A lot of issues are only political (economics, immigration, big government vs smaller government, for example). I have opinions on these, but only discuss them as a hobby.
But some issues also carry serious spiritual implications.
You are telling us that while intellectually opposed to them you will still support things like abortion and gender changing surgeries for minors.
This is saying that while a Christian you will oppose God and choose to support immoral things if doing so will advance your political views.
That is putting your hand to the plow and looking back, allowing the concerns of this world to strangle the seed that has grown.
Now....if we were just talking politics then I'd be discussing pros and cons of each political platform. Both Democrats and Republicans have good political points, and we typically benefit by a blend of each.
BUT we are talking about spiritual issues as well.
We are talking about whether a Christian should support killing unborn children if that means advancing political views they value.
We are talking about whether a Christian should support subjecting children to gender changing surgeries if that means advancing political views they value.
If Harris did not support demonic/anti-Christ actions and agendas then I believe a Christian could vote either way.
