Was Adolf Hitler a religious person?

No. He was a megalomaniac and into the occult. "Christian" is just a label if you don't walk the walk.

He had a line in god-talk he brought out when useful. In private, he was atheistic.

Indeed!As devout as it gets.It must have been an awful shock to wake up in hell!Richly deserved though.

Many people consider themselves religious, but are evil. Just look at religious people who persecute homosexuals and other religions that don't suit their religious beliefs. Religion is a con game.

was he son of a btch

He was very superstitious and into the occult. I'd classify that as religious. Religious people are certainly into superstition. Perhaps more importantly all his orders were carried out by good Christians. He didn't personally kill very many people.

Current day atheist China has the same gas chambers that Hitler had in ww2, and these atheists use them to exhume the bodies of Muslims.

There is not much difference between current day atheist China and Nazi Germany.

not really..... he was into some occult stuff..... but he was NOT... in any way.... a Christian

Very.

Yes, he was Jewish - but heavily in denial.
