Leaning of political system would be measured in degree of proposed changes. The center shifts, but even without accounting for that, democratic socialism is still not a centrist political system by any measure. Democratic socialism proposes radical changes, as it attempts to dismantle capitalist estabilishment, eradicate class structure and all that. Those changes are touching fundamental aspects of the current system, which make them, by definition, radical. As opposed to centrist position of mantaining the status quo.

I thought you had some sort of insight about democratic socialism being actually a centrist position, and wanted to hear it out, but it seems you’re either unwilling or unable to engage with that topic. Suit yourself.
