only problem with this theory is there are "conservative" people who also date out as well
When you're a conservative people you do conservative things like date/marry in group.
When you're a progressive people you do progressive things like date/marry out group.
We were one then over time became the other.
Being a progressive people means adopting progressive trends and dating/marrying out is just one of them.
