Yes. My family and church we're extremely anti semitic. They blame the world's ills on the devil and the "ACjews". As in "anti Christ Jews". Pretty disgusting. They think Yahweh used Hitler, among others to "rightly judge those that rejected his son." Unfortunately I'm familiar with prejudice and prejudicel writings.
But even if Mein Kampf, didn't say anything "too" egregious, so? If Saddam Hussain, wrote a book before he was in power we wouldn't turn to it to judge his rule. We would and do look at people's actions or lack of actions while in positions of power and control.
Anti semitic is a broad brush intended to stop conversation. Every ethnicity has people of virtue and people that are vile and base. The use of such terms prohibits acknowledging that that there are vile and base people in the Jewish community.
The first Christians were Messianic Jews who accepted the free gift of salvation that Christ offered the whole world. But it was also the Talmudic Jewish leaders who had him crucified by wicked hands. And it was the Judaizers who persecuted the early Messianic Jews who followed the Way. I disagree with your families position regarding God using Hitler to punish the Jews.
I also am leary of comments made by people who reject a writing without having read the writing. That is prejudice in the literal sense of "pre-judging" without actually knowing. I have yet to finish the book since I am still in volume 2. History is very murky in its report of what caused WWI and WWII. Mein Kampf gives a clear account of the German perspective of those interim years.
In volume I Hitler makes it clear that his attention was on resisting the advance of communism into Germany. Communism is a Jewish creation. Karl Marx was a Jew, and the Bolshevicks in Russia were foreign Jews, Lenin and Trotsky, who led a revolution against the Czars and caused genocidal destruction to the Russians, especially the intelligentsia and Russian Orthodoxs.
On the dark side, Hitler fell into the Darwinian racist point of view. There are no races. Race is creation of Darwin based upon his theory of evolution. There are only families of men who have developed ethnicities due to geographic separation and environments. A separation that is God ordained since it was God who scattered the tongues at the Tower of Babel, and dispersed the nations across the world according to his will.
Act 17:26 And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation;
Act 17:27 That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us:
It is God's will that people be different.
What Hitler saw was the same thing that Margaret Sanger proposed: that eugenics, which means "good breeding" should be imposed on humanity just as horse breeders breed horses for racing. So, like Sanger, Hitler was clearly a racist. He was not out to destroy all other "races", but to ensure and increase the German "race" which he called "Aryan".
No, I am not defending his racist point of view, but we should understand the lies that many people believe.
