Probably true if Dems were in charge, though it wouldn't be because a persuasive case against racism hasn't been made. The naturalist's worldview provides for the existence of race discrimination naturally, as Darwin well knew. It is only through coercion that slavery can continue in the modern world and only through coercion that evolution will remain a monopoly in the schools. Hence the use of the courts, rather than evidence, to stop ID.
You have it backwards. If the federal courts hadn't intervened in public schools in the South, the Dems would still be in charge.They were the party of segregation. Once segregation was gone, so were they.
A persuasive case for evolution has been made. Many people simply aren't listening.
