I suspect you know that I was not really suggesting that people were forced to go to mass at gunpoint (I was using a metaphor to make my point) But let me clarify my position anyway.
The point is that people were punished for not being Catholics in good standing (or at least for not acting like Catholics in public). Moreover if you were a critic of the regime or the Church, you were all too likely to disappear (and reappear in a mass grave).
Here are some sources to support my claims:
A news article about how the Nationalists stole babies from couples on the other side (and had them raised to be God fearing Nationalists):

A news article about how many victims of the Nationalists and the Franco regime seemed to simply disappear during the Franco years (when in reality most of them were imprisoned or killed and put into mass graves):

Furthermore women and Protestants were very much discriminated against under the Franco regime. Non-Catholics and women were second class citizens at best under Franco.
Here are some sources to prove this claim:
Here is a study done for the U.S. Library of Congress talking about how married women needed permission from their husbands to own property, be employed, or even travel away from home during the Franco era:

And here is an article from a newspaper in 1959 talking about how Protestants in Franco Spain were not allowed to hold public office, teach, serve in the military, do religious ceremonies in public, or open new churchs. As well as facing constant harassment from the authorities and the Catholic majority in Spain:

This article by the Rutherford Institute talks about how Protestants were not allowed to open schools (as well as being persecuted in other ways):

And here is an article by the Christian Science Monitor talking about how women were not allowed to have their own property, as well as being treated as second class citizens in other ways in Franco Spain:
