"Politics is a scam" ?
Tell that to Jewish people living in Germany during and after WW2.
I applaud you for your optimism but saying politics is something that can be ignored is just plain dangerous and a direct threat to every one of the things you deem important.
Interesting that you bring up Nazi Germany as an example of why we should involve ourselves in politics. I would use it as exhibit “A” of why Christians should have nothing to do with electoral politics. Don’t forget that the NSDAP won a plurality of the vote in Germany. After rising to power, adolf was probably the most popular political leader in his own country, ever. So much for the ability of politics to select virtuous and Christian leaders. What Jews in pre WW2 Germany did or did not do politically wouldn’t have mattered one iota. Ultimately the German culture of that time was looking for a NSDAP or something like it. They got it, in spades.
The lesson for Christians in my view is not to be ignorant of politics but to avoid it like we would a den of venomous snakes. Secular politics is not our mission or a way of achieving anything of lasting worth for our faith.
