Reddit specifically has many subreddits that openly dehumanise men and act as if they are lesser creatures. There is a sort of original sin going on, where men are considered evil by birth for no other reason than their gender.
There's a very small hop between "gender is in blood" to anti-trans mentality, gender roles, toxic masculinity, etc.
Really when we say men are born evil we denounce the idea of gender being socially constructed, and how we socialize men. We essentially let men, and those who raise them, completely off the hook. We ignore rape culture, we ignore toxic masculinity ingrained in boys, we ignore neglect of emotional education. Which are all very important.
In actuality, almost nobody is born bad. We socialize them in their communities in families to express that behavior. Which means we can chip away at it, slowly over time. Which we've already done to a large degree - men are so much more progressive today. Things that were once normal and expected, like domestic violence, are now denounced and demonized as they should be. We haven't fixed anything completely, and likely never will, but that shouldn't stop us from making improvements.
Example: r/womenarethings
The subreddit description:
> Women are things. Objects.
> They should be enjoyed, used, and they should enjoy this treatment without expecting anything in return.
> Women should not have an identity. They are not "I," "me," or "we." Women are "it," plain and simple.
You won't find any sub describing men like this.
Right at the top I found a message from the moderators: "This is a safe place for women to explore their kinks"
So I can only assume you didn't know what that sub was and just searched for something to justify a belief you already held.
