Google hate content policy and policy

So, I'm thinking about starting a political blog monetized through AdSense. There's only one thing that holds me back, and that's Google's obnoxious content policy. With our current political climate, this feels like something that could cause problems. With that in mind, I have some questions:

1. Are there resources that further clarify Google's policy? Something with examples of articles of what qualifies and what does not qualify would be great.
2. Will Google issue a warning giving me the opportunity to delete the content beforehand?

Let's say I write an article with a title like "Research shows that liberals are better people than conservatives": would this violate the hate policy rule? What happens if I changed around liberal and conservative?

I really want to do this project, but at the same time I do not want to cross any line and lose my financial incentive. At the same time, I do not want to self-censor myself and create mediocre and boring content for that.

Thanks in advance for any additional clarity.
