It's pointless to try to separate things as political or non-political. You always have politics when you have deep disagreement, especially on values, among people who interact.
Keeping things non-political at least implicitly means you're fine with the status quo, and sometimes a community is in agreement about the status quo being fine enough to work inside it.
There is no shortcut by simply discouraging or removing "politics". If the community is divided, there is no way around the friction. You can either fork off separate communities, or work on smoothing out the differences.
That's like saying "there's no way to remove emotion from a conversation". Of course not, emotion is always present. But adults practice emotional regulation and work hard to prevent it from interfering with relationships (i.e. not screaming when you're angry).
Sure, politics colors many people's worldview and it's hard for them to put it in a box - that means we shouldn't try?
In a better world, we'd focus on critical thinking, being less sure of yourself, openness and active listening. We'd teach people to work to think objectively and to identify the differences between technical opinions, emotional and political ones.
We wouldn't say "well, this is hard, so let's just do whatever".
