More on Heinlein

So, I am going to bast through this one because I am feeling pretty ambivalent about it and I want to get this done before I change my mind.  This novel, like others of Heinlein's I have read, has some interesting aspects to it and is a generally good sci-fi novel but also presents some elements more difficult to swallow.  Really, it is difficult to separate these difficult bits out because they are thoroughly baked into the entire narrative.
Here it is: The Day After Tomorrow is about a small military base in America attempting to resist an occupying force (Panasiatics) after they have defeated the American military and taken down the government.  Heinlein doesn't describe the war, he is just interested in the aftermath.
The base is well-hidden under a mountain and those remaining have access to a new scientific discovery called the Ledbetter effect.  This idea is pretty cool because it exploits expansions of the electromagnetic spectrum that link it to nuclear and gravitic forces.  The colonizers have no idea that this power exists and the Americans seem to be able to do pretty much anything with this new power.  This is the first cool idea.
The second cool idea is that those remaining decide to create a fake religion in order to organize a resistance against the Panasiatics.  They see that religious institutions are left alone and they exploit this to open churches across the country and recruit patriots to fight with them.
So far, so good.
Heinlein consistently dehumanizes the "Panasiatic" enemy and describes ways that the Ledbetter effect can be used to single out individuals based on race.  They can "tune" the effect to work only on those he calls "Panasiatic."  They also use the effect to shield the churches, barring anyone not white from entry.  Heinlein specifies this exclusion, essentially erasing other people of color from America, or at the very least excludes them from participating in the resistance.
The characters in the novel also use a variety of slurs against the "Panasians" that don't bear repeating.
In a previous post, I wrote about the morality that I perceived in Heinlein's work and the difficulties that I have with it.  In this book, he extends these problems.  He celebrates individualism at the same time that he wants everyone to know their place.
I do enjoy many elements of his work and believe him to be a sci-fi visionary in many respects.  This element keeps popping up and it makes it harder to enjoy otherwise meritorious novels.
