er: Your facts are incorrect. It was not the Democrats/liberals that pushed for laws that protect Sabbath observers and other minorities. Those laws came thanks to Republicans. Well into the 1960s the Democrats were still a racist party supporting the subjugation of blacks and other minorities whereas it was the Republicans who from the Civil War era through the 1960s pushed for minority rights against Democrat racists.
Secondly, even if the Democrats had some good positions 50+ years ago, that has nothing to do with today. Today is a different world. Democrats then were often KKK members (i.e. Democrat Senator Robert Byrd, etc.). Democrats then actually often opposed abortion. Today virtually no conservatives and no Republicans support allowing employers to fire employees who are Sabbath observers. In fact, it is the Democrats who have increasingly become anti-religion in recent years, often supporting laws forcing religious people to violate their religion in order not to discriminate against immoral lifestyles.
