The biggest problem is that we, as humans, are fed all kind of nonsense to induce polarization. All news we hear is that it's either black or white, capitalist or communist, Republican or Democrat. The biggest issue is the 2 points of vew most people see.

It even goes so far that in countries with a limited democracy (2 party system) a lot just refuse to see the other point of view, vote for 'their party' as the other is worse in their opinion,... (choose for the less bad one instead of a mninor one you really support, just to keep 'the other' from winning) For example, in the US the news is never independent, you either get a pro Republican or pro Democratic point of view. Social media keeps people even more in their bubble, so it's even more 'us against them'. Most forget that a good working democratic system can't exist with only 2 points of view, you need at least 3.

Why do I say you need at least 3, as that way not a single, one-sided view, can dictate what is the truth. With a 3 way perspective, all will need to talk to each other to discover what is the real situation. That's why the 3D world is useful as well. As we have history and science, I'd say we even need a 4th dimension to consider as well, time. What is good now may prove a bad idea for later generations and what seems bad now may be ideal later.

But alas, as long we we are fed the idea that either capitalism is good and communism is bad (or the other way around) and ignore a go between like say a liberal system with a socialistic base we'll keep this mess. (same like the 2 party systems in US ans roughly in the UK) Same about 'west vs china'.

Ok, the Dutch political system is broken up way to much. The last election in 2021, 37 parties were on the ballot of the 89 wanting to register) and we have a more fragmented set now (next election 22 november), but they are working together, as they need to. (even the biggest minority has to work together to get at least a few points of their program supported) That's a result of 3 major parties each not being big enough to rule with only 1 of the others, so they either had to work together with each other (all 3) or find support from smaller parties, so the most extremist ideas (religion based state, denying abortion, closure of borders for refugees,...) were kept in check.

Between extreme left or extreme right views (which are pretty similar), there are loads of moderate views as well that need to be heard and could prove a a lot more beneficial to humanity then just one of the extremes.

Edit: to get back on topic, there was a comic I just can't find that shows the biggest discrepancy of the anti-abortion movement. When unborn 'All life is sacred', but after birth, it's 'you're on your own'. Unless a community doesn't want to solve the latter (make sure everybody can have a good and healthy life, they have no say what so ever in the 1st matter. (and even if they do solve the latter, it's still that way) Alas there are to many people that force their view upon others. (and no, pro choice doesn't mean you have to have an abortion, they just state that it's your choice, not somebody else's)
