It's not a conservative meme. 4chan trolls != conservatives != The Right != Republicans != ... Almost nothing fits neatly into a bipolar spectrum of "us vs them" and 4chan culture is mostly about being where the normal people don't want to go.

On /b/ you can find posts complaining about Jews controlling the economy, trans people swapping pictures, memes about niggers cucking white bois, incest fantasies, celebrations of school shootings, people claiming their favorite anime characters as waifu/husbando, complaints about how this is all cancer and needs to stop ...

There is no unified message that would fit into mainstream politics.
