Several issues with that thread. For one, they only apply this to nerds (who aren't even really considered outcasts anymore. Being a nerd is pretty normalized nowadays and is even seen as a positive by most people), those with autism, and incels. In reality, being an outcast applies to a lot of people outside of those demographics, including a lot of marginalized minorities. To gatekeep who is an outcast and who isn't, as though being an outcast isn't something can apply to anyone for a variety of reasons outside of the ones they listed is pretty dumb.
Then, you have the question of what do they mean by "destroy society"? Do they mean they want to destroy the systems that are place in our society? Do they mean they want to just destroy stuff in a more literal sense, like destroying things and terrorizing others? I'm going to assume that refer to the systems in place and our values for rest of this post, but I will say that just saying "destroy society" is incredibly vague.
They also provide no insight into why or how they are going to "destroy society". A lot of people will say shit like that while also still wanting to uphold the systems and values within our society that specifically benefit them, even if they harm others. "Destroy society" seems to just be an empty phrase from them to use in order to sound cool and rebellious, rather than it being something they actually want to do. Nobody in that thread says anything of value. They just say a bunch of empty bullshit vague bullshit.
If you want to destroy society then you have to do so in a thoughtful manner. You need to take the time to understand what you need to destroy, why you need to destroy it, and what you need to try and put in its place. Rebelling against something only works under the guise that you've actually put thought into why you are doing it and how.
For example, if your an incel and you truly want to "destroy society" then you should look towards rebelling against the gender expectations put in place by the patriarchal structure of our society rather than just spending your time hating on women and feminists and arguing in favour of those expectations and values.
I'd personally would love for society to be destroyed and restructured into something better for everyone, but that's something that takes time to do. It's something that requires that you've taken the time to both reflect on yourself and the world around you. It needs to come from a place of love and care for others. That thread is completely worthless because these people don't actually care about destroying society, they're just saying shit with no thought put into it.
