I'm sure OP didn't mean it but comparing anything happening with dem politicians to the underground railway amounts to denialism of white supremacy and the enslavement of African people.
African people were forcibly removed from their homes. Their descendants were owned from birth. Both were forced to perform labor of various sorts and lived cradle to grave without any semblance of legal rights at all. This was heritable, passing from mother and/or father to all children. It was not only illegal for a white person to assist them to exist the situation, it was legally required to prevent them from doing so. Which is to say nothing of the penalties on any Black person caught escaping or assisting an escape.
The underground railway was a system of attempting to assist a class of people to gain freedom in defiance of every law and social convention, one person at a time. It was an act of racial, class and national treachery far beyond anything I've ever heard any democrat even contemplate.
Therefore, comparing any contemporary situation serves only to diminish the gravity of the underground railway. Which was not just about going somewhere else for political reasons.
Need a different analogy.
