Maybe there are games I’m just not interested in playing.
There are many different ways to frame the human experience. “Democrats v. Republicans” is only one.
Your work is directly linked with exploitation and oppression of people around the world, in almost every industry. The tech industry is directly linked to child slavery in the Congo, mining Cobalt for hardware. And tech players have a big role in worker's rights in the US too, think about Uber drivers. There's every reason why tech workers should use their united power to do something about these issues.
Ethical values impacts literal matter of life and death for millions of people. This is true. Ethical values differs also from people to people and is a deeply aspect of personal identity. As such, challenging coworkers on a political level also means challenging coworkers personal identity, and that just something which the workplace is poorly designed for.
Possibly. It's certainly possible to experience "religious discrimination" as a result of not being religious. The right to be non-religious is essentially a political one.

That's an extremely narrow view of what politics is. I can't blame you for that because a lot of people want to jam everything down to that narrow view, but there are plenty of things in politics other than factionalism.
