No

1) Authoriitarian and fascist governments have been normally taken over by force, political manipulation (rather than popular vote), violence, by removing the opposition candidates, by voter coercion and by vote manipulation (not exactly "voted in" democratically). There is a lot of material online about this, unless you have a political history book handy.

2) The US colonies did overthrow their authoritarian colonizer, but thereafter were NOT "fascist". They formed a representative democracy that kept the power among the elite, which was not authoritarian, though it was somewhat oligarchical.
