Separation of church & state didn't come from our founding fathers it came from a Baptist preacher named Roger Williams. The State dictated the Church of England rule that people made to attend worship services & live by the 10 commandments (legalism) Roger Williams fought against the State rule stating that as Christ has made us free we are free indeed. Williams as well as other great preachers such as CH Spurgeon understood the teachings of the bible that the law was given to show man of his sinfulness & that Christ came that we would be free. this is Grace. Thats the true reason of your separation of church & state, not the crap being shoved down our throats now.
As far as slavery. The democrat party are the worst slave traitors & the men behind it are named Louis Farrakhan, Jessie Jackson, Charlie Rangold & Al Sharpton who made millions to keep minorities in bondage by lobbying gov. to give welfare to minorities. When a black man sees this as a sham & decides to go out & prosper on his own by hard work & starting businesses employing others & giving back to communities in a positive way, then he is labeled by democrats as an Uncle Tom!
It's always that you hear how the blacks were treated during slavery. Yea I agree with that but some were treated well. Who taught these people English? It was our Gov. that made laws forbidding owners to teach slaves to learn to read. Funny how also those mean ol slave owners taught the gospel to slaves & you see all these black churches from years gone by! I've been to Kenya and blacks live much better here than blacks over there. The children of Israel had a tough time in the desert for 40 years, Sometimes there needs to be struggles to get ahead. Get over it & enjoy!
