Having just read a book about Thomas Jefferson, I couldn't help but compare the politics of then to now. "The more things change, the more they stay the same".
In his day, it was the Federalists vs. the Republicans--conservatives vs. liberals. (Today's Democrats were yesterdays Republicans.) The bitterness, insults, and accusations were much the same, if not worse, than they are today. Vicious. Nothing will ever change, so we might as well accept the fact that the two sides will always disagree and continue fighting. I'll just sit back and watch.
Jefferson's religion was personal. He was a Deist--not a church member (although I'm surprised he wasn't a Unitarian). His lack of outward faith prompted "the right" to accuse him of being an atheist. Public statements and letters proved otherwise, although he did urge others to think for themselves and use scientific reasoning to pursue "the truth".
Our third president was often contradictory, being against slavery, for example, yet owning (and sireing) slaves, continued to his death. Still, Jefferson was a great man, a primary force in the making of our country.
