Debatable. One of the core ideas of democracy is to protect minorities. Democracy has been built around the concept that a majority cannot restrict basic rights of minorities. Arguably no one should be allowed to create a system which allows the violation of basic human rights of minorities.
Is that still a minority? I invite you to introspect more. It's not complicated either.
A voting minority cannot by itself gain power in a democratic election.
A population minority may vote with, against, or mixed versus the eventual majority. It is not the same as active participation in voting.
This is the essence of gerrymandering and why only ~10% of US house races are competitive. It's related to why there are only seven swing states in the US for our only national election, which should be changed to a national popular vote.
The idea that democracy is synonymous with the current neoliberal order is nonsense.
