I'll never understand why anyone would think posting this is a good idea. I love how even the Arianators are calling this user out. I don't understand stan wars and I never will. Especially when Ariana and Selena are actually friendly with one another, as far as I know.
But honestly, I think if anyone saw a celebrity they disliked, they'd still take a picture or ask for an autograph. Like it's still a famous person right in front of you
