Quote
1: a firm adherent to a party, faction, cause, or person
especially : one exhibiting blind, prejudiced, and unreasoning allegiance
political partisans who see only one side of the problem

You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.
