Part of standing up to Nazis like Buchanan is standing up to everything they are all about--and a big part of it is homosexual perversion. There are a number of reasons why Buchanan is strongly suspected of being a closeted gay man. He was rejected from the draft for having Reiter's Syndrome, a joint disease usually caused by untreated chlamydia. In the 1950s, chlamydia was quite rare in heterosexual white teenagers. That wasn't the era where nine-year-olds were having oral sex at recess and getting Gardasil shots. Buchanan is married but has never had children, and his wife has had an essentially nonexistent role in his life, despite three presidential campaigns--even though he is constantly berating whites for not having enough babies. For the first half of his political career as a candidate and public speaker (i.e. pre-1999), he was fanatically and ridiculously anti-gay, but then almost overnight at around the turn of the millennium completely dropped the issue. For being supposedly so homophobic, he has a close relationship with fellow anti-Semitic paleocon Justin Raimondo, who happens to be a very open and proud homosexual. Then, there is "soft" evidence that Chaim and various JTFers have pointed out, such as his demeanor, occasional strange looks and expressions toward other likely homosexuals when on his news programs, etc. Finally, while this is no kind of proof I admit, he has a rather unusual squeaky little voice for an old man!
In the case of other well-known Nazis, such as Frank Weltner, Joerg Haider, Ernst Rohm, Richard Wagner, Yasser Arafat, and Kevin Strom, their sexual orientation is a matter of fact and beyond any shadow of a doubt.
I'm sure that your reply will be that it is not fair to use several degenerate hardcore Nazis to paint a bad picture of homosexuality, but my response to that is to look at Jewish self-identified homosexuals. In the United States, we have such individuals as Tony Kushner and Harvey Fierstein. In Israel, the sodomite-rights movement overwhelmingly identifies with the Arab Muslim Nazis that would murder them in a heartbeat. Do you not remember in 2006 and 2009 when these degenerates held huge rallies in the streets of Tel Aviv expressing solidarity with Hezbollah and Hamas, respectively? This occurred even though Israel is by far the most tolerant and progressive Middle Eastern state when it comes to homosexual "rights". The last time I checked, the Arab world didn't treat open, self-identified homosexuals (at least the effeminate kind--we all know they think that masculine homosexuality is just fine and dandy) all that well, so surely their sympathies couldn't have come from a desire to identify with gay-friendly regimes.
