I don’t agree with neither of you but dude, you’re just being dense here. Politics is not a direction where the center is still and the two opposite sides are moving. It’s a matter of ideology and values: centrist values are moderate, try to reconcile capitalism with civil rights, a moderate economic policy where the state intervenes where it is deemed necessary and in general a centrist mediates between polar opposites (at least ideally). If you say centrism doesn’t exist you’re living in a pre-fall of the USSR world.
If anything, now everything is centrist, and what’s worse is that centrism is slowly being absorbed by right wing values (free market, family, public decency, right to defend oneself, more power to the military) whereas leftist ideals were left to rot in a basement for 30 years and now all leftists can babble about is SJW fodder.
I know you hear a lot of leftist propaganda but the whole world is moving the opposite direction. We need class struggle and we need to bring back the middle class.
I'm not sure what possible argument would work if you insist that there can be two different points that don't have a midpoint. That's primary school geometry.
In the US there are right wing and even more right wing. The Overton window moves so fast more and more to the right that it has a visible Doppler effect.
