Politics are politics no matter whether you happen to agree with them or not. If politics are off-topic then so are all those Guardian articles and flagging them is the correct approach.
Mind you, I have my disagreements with this policy since I know nearly everything has been made political. Be that as it may the policy should be applied without bias for this forum to not devolve into yet another Reddit clone.
Political content of any kind is considered mainstream and off topic by many people here, and thus unlikely to lead to curious and intellectually stimulating conversation. Which is the only kind of conversation we're allowed to have. Good hackers aren't supposed to find this interesting.
If you want to keep discussing these things, it really is best to just keep your head down and accept that the thread will be flagged at some point, and when it's dead, move on.
I agree mostly, however the mods repeatedly allow high karma accounts to flame bait and continuously makes exceptions for the worst political threads. The guidelines are very vague and allow for any number of interpretations.
The rules exist through the zeitgeist of the community, not through any text about hacker, novelty, etc.
