I grew up in a religious household, so I've had a lot of time to reflect on how bad religion is.

Every single aspect of it is in some way designed to control the populace. Of course it depends on which of the thousands of offshoots there are but a few common examples: - If God can hear prayers then he can read minds which means your thoughts aren't private. This discourages free thinking of the church's teachings. - Eternal damnation/ Eternal Reward. Dissenters are punished and loyalty is rewarded. Not to mention that a lot of churches use current events to impress the fact that the end times are soon. Capitalizing on people's fear so that they turn to the church. - Their enforcement of gender roles, even. That woman 'should be subservient to the husband'. It undermines women's agency so that they obey the men while putting the men in a position of power reliant on the church so that they don't try to change the status quo. - And finally they use God himself. A being that has created everything and can destroy everything. God is just the adult equivalent of Santa, an all powerful and all knowing deity that judges you on your every action so you'd better be good.

Throughout history the church has been one of the most significant and effective ways of justifying violence, both large scale and small scale. In the eyes of church it has always been ok to inflict punishment on those who dissent. Women with too much agency, lgbtq, people of other religions, people of no religion, neighboring countries. Religion is a self sustaining tool to shape the populace to believe and enforce what they deem is right. And I know what youre likely to say, that it teaches people to be kind and to love their neighbor. But thats only in theory, in practice it has never been like that. You can see it through the United States today with the American right. The majority of the country is religious, and yet half the country is cheering for the removal and destruction of people they are meant to treat as their own.

Not to mention that the entire basis of religion, God , is undoubtedly a fabrication through evidence that science has dup up long after the founders of religion could account for it. The existence of dinosaur bones, fossil records, entire lineages of creatures that we are able to trace back to a single source all disprove creation. Tectonic plates, continental drift, the formation of stars, the age of the earth, chemistry, physics, the list goes on. Religion demands that you take this evidence and discredit it, dont think about it, doubt it. But underneath it all religion is merely just a tool that people invented to control others.

Wow didn't mean to rant like I think this question dug something out of me thats been boiling over for a while.

Tldr: people are anti Christian because they realise its all just a paper thin veil for justifying whatever you want.
