It’s from a shitty rap song. What, do you believe everything you hear in a rap song as evidence? This isn’t moving the goal posts, this is more proof the Sun is absolute trash at putting things in context. Listen to the fucking song. It’s awful, but it’s completely consistent with him being a poser talking tough in a rap song. He also says he “buried bodies with Gacy” in another track, do you believe he’s also some notorious serial killer?
Shit like this isn’t a good source for the intentions of someone, especially when it was posted years ago. Find something closer to the date of the incident where he’s claiming to be a terrorist. A single lyric in a bad SoundCloud rap isn’t proof of being racially motivated, it’s proof of being terrible as a SoundCloud rapper.
