This is actually laughable, but I’ll point out your own hypocrisy.
Anti theism is desiring the eradication of all belief in God and mandatory atheism. By default and nature, it is bigoted and worse than everything you listed. But sure, let’s entertain this anyway.
The aim of the Crusades were about taking back the Holy Lands from the occupying Muslim forces. Sure, religion was involved, but the same stuff happens with National ideology. Like Russia “taking back” Crimea in 2014. So getting rid of religion won’t stop things like this happening. Throughout modern history, most major wars were based on a secular political ideology, notably the First World, Second World, Cold, Korean and Vietnam wars.
Second - Molestation scandals. These happen in any organisation, and like wars, aren’t inherently religious. Of course, large churches were a good target for child molestors, but the same thing happens with schools, generic celebrity stuff and broadcasting corporations. Sometimes on a bigger scale than the scandals in the Roman Catholic Church. Anything that gives anyone positions of power.
Third - Let’s list some prominent anti-theist regimes.
USSR - 1.2 Million killed in the purge.
People’s Republic of China - “Fatality estimates vary across different sources, ranging from hundreds of thousands to millions, or even tens of millions.” (Of deaths in the cultural revolution). Christianity is still persecuted to this day, and the state can be described as anti-theistic.
Nazi Germany - 6 million Jews killed in the holocaust. Very arguably anti theist as Hitler tried to eradicate Jews and suppressed Christianity that wasn’t theologically liberal in his favour.
Obviously not everyone was killed in the precise name of anti-theism, but it still shows that the problem isn’t religion, which anti theism makes it out to be.
Lastly, in the People’s Republic of China, people are often shunned for divorce and homosexuality, and it’s still a very atheistic country.
For myself, I have never shunned anyone based on sexual orientation, gender identity or relationship status. I have never called for any of these people to be killed by the state for these either. I do not believe the state should be enforcing Christianity when someone’s immorality isn’t hindering anybody else (Such as Homosexuality or Polygamy) Yet if the anti theists had their way, they’d have me persecuted and likely killed because I am a Christian.
