You’re exactly right. Their strategy was to tease apart American’s cultural mainstream fabric into isolated victim groups (identity politics) with the hope of cobbling enough of them together to win the election. Real Americans sniffed it out because it caused so much visceral discomfort, and was antithetical to the credo of “E Pluribus Unum.” They rolled the dice and lost everything, and likely for many years to come.
Almost there - just move one level of abstraction higher, and you'll have the entire picture. Essentially, the NWO financial/media globalists wanted complete control to further maximize their own power & wealth.
In order to achieve that end, it was first necessary to destroy cultural cohesion among individual nation states. Uncontrolled (illegal) immigration, cultural marxism, identity politics and controlled speech - aka PC - were the tools of 'divide & conquer' used to reach those objectives.
We should never forget that both the GOP & DNC were locked into this strategy - the uni-party was a real threat to our collective liberty & freedom. Recall how much push-back the Don got trying to move the party back to the center.
While he was successful destroying this evil ideology on he right, the left hasn't yet fully realized that their moment is over. Now they to will have to re-group and focus on national issues if they wish to regain any semblance of power.
