And I won't even attempt to dissect every way that the rest of your unhinged rant because I have better things to do than disprove things you could find out in a matter of minutes if you have an internet connection and anything more than the attention span of a goldfish. It's blatantly obvious you're just another Democratic pawn with Trump Derangement Syndrome, and i'm not even a Trump supporter.
"Democrats supported the civil rights"? Uhm, no they didn't. When the civil rights bill came before the full Senate for debate on March 30, 1964, the "Southern Bloc" of 18 southern Democratic Senators and one Republican Senator (John Tower of Texas) led by Richard Russell (D-GA) launched a filibuster to prevent its passage. That is a blatant lie on your part.
The so called "Party shift" only refers to two things:
1.) The Political party's foreign policy stances; Republicans became open to interacting with the rest of the world while Democrats wanted to isolate America from everyone else.
2.) The general locations each party is found in; Newer generations of southerners were raised under the effects of the civil rights movement and saw the aftermath of their Democratic pedicessors actions and therefore decided to become Republicans, while Democrats migrated up northward to avoid the backlash of their racist behavior and to hopefully take power in larger cities. (Which they obviously got.)
