the republican party of the 1800's is not the republican party of today. the democrats of that time, the slavers, the states' rights extremists... the people who fought to keep slavery are all incorporated into today's GOP... they ran to the GOP after the civil rights' act.
All I can say is "wow".
OK, now for a little history lesson. You did not say
which Civil Rights Act, so lets go through them, starting in 1968 and going backwards, shall we?
Civil Rights Act of 1968, 71.2% of Senate Democrats voted for this legislation, 90.6% of Republicans voted for it.
Voting Rights Act of 1965, 73% of Senate Democrats favored this legislation, and 78% of House Democrats. Of the Republicans, 94% of Republican Senators and 82% of House Republicans approved this one.
Civil Rights Act of 1964, 69% of Senate Democrats and 61% of House Democrats approved this legislation. Meanwhile, 82% of Republican Senators and 80% of House Republicans approved this law.
Shall we continue playing? The votes are a matter of public record, and easy to look up. Funny how you are making claims that are the exact opposite of history.
Feel free to look it up, see for yourself which party had a higher percentage of approving votes. This is why I tell people over and over to not just parrot things they hear from others, but to do real research themselves and find out what happened.
