Racists used to be proud, but now nobody wants to admit it. My neighbor is as alt right as you can get but he's not racist, it's just those brown people.... Those darn Nazis ruined alt right extremism for everyone.
Sodomy is a sin in the bible because the Romans were in power and they were open about all forms of sexuality including pedophilia. Christians didn't want their oppressive rules so of course they preached anti Roman values. The Romans are the bad guys in the bible until they embraced christianity. The bible is anti Roman propaganda.
For 2000 years, the new testament was the guide for living a good life. The problem is that humans are fallible and choose which actions to take and which beliefs are important. Now we have a new source of information called the internet. On the internet, all of these groups who have been oppressed for the past 2000 years by Christians now have a voice. Information on slavery, colonization, sexuality and different religions are all available for the world to see and the alt right hates it because for 2000 years they created their own white oppressive empire and how dare anyone disagree with them.
History repeats itself. The oppressed become the oppressers because fear and hate are easier than empathy.
