Like you, I view the damage done to this country by the Left beginning in the Wilson and Roosevelt administrations as being the foundation of many of our modern troubles, accelerated after WWII by their embrace of communist and Marxist fundamentals.
In my opinion, those were first hidden and subterranean during Joseph McCarthy’s martyrdom, then more open during Lyndon Johnson’s administration, through Vietnam, and then, finally and fully open with Clinton and Obama as the 60’s radicals moved into the upper echelons of power.
During the Clinton administration, they did a kabuki show to hide it, and during the Obama administrations, dispensed fully with any subterfuge.
During all these years, there was the occasional person on the Right like Joseph McCarthy who stood up to fight, but most of the time, the Right didn’t rock the boat and let things go along so they could get along, IMO. Nobody wanted to upset the gravy train.
The Left liked to tout Truman and people like Scoop Jackson as being staunch anti-communists, but both of those men showed that Party was much more important to them than Country between 1950 and 1953 when McCarthy was fighting communist infiltration into our government.
And even though we have had our issues with those on the right who embrace globalist policies and may have been willing to surrender portions of our national sovereignty to entities outside our country, I don’t believe there have been a lot of people on the right who have embraced such anti-American concepts, racism, and identity politics as those on the left have.
And, it isn’t even close.
But I do believe the Right should have stood up more often in the way Trump largely appears to be doing now.
The main probably with that is: Along with most other traditional American institutions...."The Right" has also been largely infiltrated and commandeered by the left.
