Hitler and the Nazis never hated Muslims or Arabs. They were never persecuted by the Nazis. The Nazis' main enemies were always the Jews, the Freemasons, and the Gays. These were the groups persecuted and killed by the Nazis. But never Muslims or Arabs. So it makes absolutely no sense for a neo-Nazi to hate Muslims or Arabs. Ultimately, Nazis and Muslims have the same enemy: the Jew.
It should also be remembered that a number of Nazi officials and collaborators found refuge in Muslim countries after the fall of Nazi Germany.
If u/towards8 wanted to make Muslims look worse he wouldn't do the occasional glorification of Muslim killings, he'd go all-out on glorifying the humanity of the ahadith about Muhammad's relations with his two grandsons and other minors. Better to just say he's a Muslim masquerading as someone sympathetic to Christians who pretends to care about them getting the truth.
The other two I needn't comment on, but they have quite a different history from towards8 and his apparent predecessor who is named in my files.
Jewish subversion can be subtle. Doesn't always have to obvious and they don't need to promote things people already know about. Subtle subversion always gives better results. In addition to creating a multitude of accounts to back each other up. They are willing to create a large number of accounts to swamp the discussion with it.
