Then, for the most part, you aren't going to be taken seriously in politics because you're fundamentally not interested in the primary cleavages in US politics going back to the founding, particularly on race.
Manufactured cleavages, you mean. You might do yourself well to acknowledge the 56 years that happened between 1876-1932 in a context not limited to "Jim Crow". The key points of which being the stolen 1876 election, Compromise of 1877, and Gilded Age particularly in the north.
Because god forbid we acknowledge radical Republican corruption and attachment to robber barons and machine politics dovetailing neatly into convict leasing for northern industry, the deliberate and targeted hiring of black strikebreakers to divide and stoke racial tensions between labor and civil rights (actually, God forbid liberals ever admit George Pullman and his company existed at all) for thirty years culminating in the Red Summer, wide scale defamation and suppression of labor and reformists throughout the period, and the first Red Scare. God forbid we admit "liberal" Republicans sold the South down the river and condemned black Americans living in it to a century of Jim Crow to ensure robber baron-friendly Hayes took office and not the reformist Tilden.
Oh no, we're a kinder, gentler, more accepting nation now, who would never be so foolish collectively as to repeat the mistakes of the past...right?
It's not like the civil rights movement started during Eisenhower, he embraced it to the point of deploying the Guard to ensure civil rights in the South, and two civil rights acts (however weak) were passed under his administration. It's not like JFK simply talked a big game about civil rights but sat on his thumbs and stymied civil rights legislation behind closed doors, only having been prompted to action being shown the power of black voters as a bloc. It's not like LBJ was behind closed doors a stunningly vulgar and emetic racist, forced to action to preserve JFK's legacy and motivated out of raw opportunism.
And even then, the age of felon disenfranchisement and mass incarceration was hot on its heels, ushered in by the "war on drugs". You're incapable of seeing this in any context other than moral, when you ought to be looking at it economically: American industry demands a cheap labor base in the form of a permanent underclass, and a permanent underclass American industry shall have. Slavery never stopped, it evolved, and it should be no surprise which group of Americans are left holding the bag.
Here's where you go completely off the cliff. You want to pretend like most others do there have "only" been "two" realignments. No. We're in the sixth party system, and the writing's increasingly on the wall we're transitioning into the seventh. To what you refer as the "first" realignment is the
third party system, and what you don't want to admit was the period was marked by Republican corruption and Gilded Age corporatism. To what you refer as the "second" realignment is the
sixth party system, and you want to pretend the fourth party system (the Progressive era) and the fifth party system (the New Deal coalition) just didn't happen, because to admit that is to admit technocratic corporatism isn't the hot shit you're implying it to be.
And Democrats aren't a force for progress, they're a force for the status quo. That was true in the '60s with black Americans, that was true in the '00s for same-sex marriage, that's still true today for the greater LGBTQ umbrella. Funny you seem to forget, or don't want to remember, Democrats were the party behind DOMA and DADT, and fought on that hill until the point polling numbers showed beyond doubt Democrats
would lose legitimacy should they fail to act. Democrats had to be forced to push for civil rights, Democrats had to be forced to push for marriage equality, and they'll have to be forced to push for gender equality.
So no, I don't think I will stand for being "well ackshuallied" on this one.
