You know, comparing the family to a cinder block is kind of degrading. Ugly, mass-produced, incapable of resisting the elements for more than a couple of decades. Can't you think of anything more noble?
Also, if there was a rise in homosexuality in the Weimar Republic and that was a problem, it sounds an awful lot like you're saying "good job there, Mr. Hitler, killing off all them gays that were decaying your society. I mean, the Jew thing, I'm kinda ambivalent, but pink triangles? Fuck yeah."
...that would be consistent, I guess, but it's a little blunt. Though I guess that's why you'd come at it obliquely like that, but even so, how does that help your argument?
Maybe you're trying to say the Nazis, who arose under the auspices of the Weimar republic and then took it apart, were gay. Because gay people always kill all the gay people. It feels like that's what you're trying to say, it's just that that makes so little sense that can't be what you're trying to say.
