Yeah, I think here it’s more referring to the general vibe of isms. Defined things people follow or adhere to. Isms can’t blanket a society because everyone has different ideas, needs, wants, priorities, beliefs, thoughts, etc. Democracy is a format for these to be heard so progress can be made with everyone involved, not just a single person’s idea on how things should be.

I get it, but “ideologies” isn’t very clear.
