Old Reliable

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.)

Parties shifted primarily in 1960’s when Democrats supported Civil Rights and Barry Goldwater Conservative branch absorbed the Racist and malcontents from Democratic Party.
Republican Party evolved in 90’s when Fox News creates never ending Right Wing propaganda. Rising Popularity for pundits, and Radio shows such as Limbaugh and Alex Jones merged slowly until Trump and the creation of the modern Trump supporters was spawn.

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.

You’re Right, they couldn’t except Civil Rights because they were Conservative Racists . That’s when Barry Goldwater and the roots of Trumpism were born. The Democrats from Southern states switched parties to become the Red states they are today.
It’s not Rocket science

I'm going to say this again, but slower. 18 Democrats and only 1 Republican opposed the Civil rights act. You have no argument for it being the Republicans that are the racist.

Your confusing 1964 Southern Democrats with 2020 Southern Republicans
They are one in the same. They switch sides in 1960’s because they couldn’t except Black being equal or social changes.
Same as today. Except now, Republican are Trump
Supporters.
You can’t except it? Stop posting.

Toe it's accept not except.
