So he’s not only a bigoted racist homophobe, he’s stupid as well.You are responsible for you as a person and you alone. You are not responsible for the upbringing or the thoughts and conduct of those in your life be it friends or family. That's like saying a friend/family member breaks the law and goes to jail, you to are guilty by association just because you know that person.
Nizam, unfortunately, didn't have the sense to wipe his socials and make them private like the vast majority of the bands friends have done before the doc was released. He's clearly not the sharpest tool in the box given how invasive Louis's fandom and the 1D fanbase in general is.
If it was me and I was appearing in it, I'd have gone through my socials deleted anyone I didn't know personally etc, and locked them, months before the doc was even announced knowing how Louis's fans are.
Louis, you need better friends!
