honestly i think the reason this rhetoric has been so prolific on tumblr is because the user base is largely very impressionable and sheltered people who get most of their opinions from the internet, and i don’t mean that to be a form of shaming or anything, just a fact that sets the scene for the information breakdown that had to happen for this to be such an issue on here. many of the people on here never bothered to think about or learn to understand why things like pedophilia and incest are frowned upon so heavily. they just know that they’ve been told “it’s bad” so when someone comes along with a big platform full of like-minded people, who at a surface level sound well educated and smart, and starts saying “you’ve been told these things are bad because of christian conservative puritanism, there’s nothing inherently wrong with this stuff! unlearn your biases!” there’s no argument these people can think of for why that isn’t true. because they didn’t bother understanding why these things are so terrible. they blindly trusted the shallow morals they were fed growing up, and because they never interrogated those morals to either change or bolster them, they’re easily persuaded into another opinion, just as blindly. it’s the same way someone whose only opinion on trans people is “trans rights!” can easily be radicalized into a transphobe years later. they don’t have any core principles to ground that belief, and were easily swayed by an argument saying the opposite of what they were ignorantly parroting
