Justifying a Coup d’État in the Name of Democracy?

Why is there so much resistance to call the forced resignation of Bolivian President Evo Morales by it’s name? To call these events a coup and at the same time to justify and/or being comfortable with them would involve an express rejection of democracy as “the only game in town” and amount to normalizing non-institutional and violent means for the handover of power. The case is a challenge for comparative constitutionalism in general.
