I don't think it's fair to say they don't love the country. They simply grew up in a different world entirely. That generation and to some extent Gen X that came of age and lived during the Cold War grew up in a security environment that us younger folks just can't even begin to imagine. Existential destruction from a "bolt from the blue" affected everything from housing policy to religion. It's the primary reason you saw Southern Baptists marry themselves to the rapture theory in the 1960s. It was a way to broadcast an illusion of control over a situation no one had control over. When the SU fell apart many boomers simply never adapted to the new world. They looked for something to fill that bucket of existential dread because they knew no other way to be.
Obama got a lot of flack for describing America as an "idea" much to the chagrin of conservative Boomers, but they largely made his point for him. They worship the idea of America that never really existed in the first place outside of a carefully cultivated image. I have members of my family still alive that didn't have indoor plumbing until Jimmy Carter was in office. The 50s and 60s weren't all that great in most places.
That Rapture theory as you call it. Aint some new,whipped up idea from man or some Coop relegious denomination from the 1960's. No offense but you are a million miles off the mark on this statement.
Also when folks talk about the 50s and 60s. True there was way less conveniences than now. Most households where blessed to have 1 car, not 2. Indoor plumbing etc. But most 18 an unders also had both biological parents living under the same roof. When they listened to radio, tv if lucky enough. There was a common decor, no profanity. Family unit was strong. Which is the main building block for everything else (churches,schools,workplaces). FYI,God ordained the family , before he ordained the church. When the ole nuclear family started getting disengrated, attacked, broken down over time post 1970. That is what has catapulted us to where we are today. Even in the African American Community as America was moving away as a whole from segregated society, turning away from its sins/errors. The family unit was so strong,thats how they made it, stayed together through those 150 years of oppression. Unfortunately now and not just the African American community,but all communities in America today,the Family has been beaten down and re-invented on purpose. The reason being to weaken America and move toward a globalist society. The ole nuclear Family is the sole foundation block That propelled America to become the powerhouse it became.
Today 80% + in the African America Community and right at 70% of Caucasian kids under 18 years old, DO NOT live under the same roof with both biological parents.
So you ask me, we where way better off then as a whole than we are now, despite the lack of technology,modern conveniences.
