Good points here. Yes, the vast majority of gerrymandering is from the left.
Opinion follows so if disinterested, tune out now:
Here's why: The Frankfurt School identified that the economic causes that precipitated the Communist Revolution would not work outside of an agrarian society. The strategy was then changed to target 'classes' of people and 'class warfare' became the chosen path to that Marxist/communist/socialist/progressive "utopia."
The more normal Democrats have all but disappeared. In actuality they have mostly become the neoconservatives borne out of the Reagan Democrats. Bad but just not as bad as the far left which is ALL that remains in the Democratic Party. Look at 'Pocahontas' Warren for example since we are on an Indian theme.
Once classes are constructed, grievances real or imagined are supplied to rile up and anger the class. Examples of the classes are everywhere: black, latino, Native American, LGBTQEIEIO, Muslim, with more popping up everyday.
Once the division is accomplished or exacerbated what is needed next is voting power. This is the whole purpose of gerrymandering. Group together members of a class so that the divisive nature of these politics can be amplified at the ballot box. This is all couched with the idea that they are just supplying a voice to the underrepresented. This stated purpose is merely a smoke screen.
The real purpose is DIVISION! Divide the country in order to effect radical change.
Class warfare and identity politics are, at their very core, evil and destructive. The hope of proponents of this ideology is that a fair utopian society will rise from the ashes of this society much like the Phoenix. It's never worked and never will. Just remember that the most costly phrase in history monetarily and in blood is the phrase,
"This time it's different!"
Did not the eight years of Obama teach us anything?
End opinion
It is impossible to unify a country when your goal is to divide it,
FWIW,
