Mm Colonists being specific to religious persecution? Nice one American High School education system.
Sadly, that is incorrect.
There were indeed SOME American colonists who were persecuted and moved to America due to a narrowminded BRITISH society.
But, what about Spain's colonies? Religion was only part of the factor, and in many cases not even the main one for minor nobility who found themselves living in the new hinterland of Old Castille, instead of the newer Castillian territories or southern territories.
Portugal? Partly religious, but also mainly for trade.
France? set up trading posts and colonies that were for the most part unrelated to religion, except for the roman catholic priests they brought over.
Britian? A number of different reasons, what you might not know is America was ALSO a penal colony, one of the reasons Australia was used, was because the American penal outlet had become lost to them. They also attempted to set up trading posts. These were mainly government sponsored or initiated due to trading concerns.
Colonists should be a part of three sliders.. Economy, Social Policy, and Naval /Land.
They should all give bonuses in the appropriate (Merc.., close-minded, Navy based) side, but not so much on the negatives, except for land based.
For example, land based powers like Austria should be literally unable to colonize, unless they put points in their naval slider.
