Gross. Not that you laughed at a bestiality line, but that you call your self a normal girl. What's normal? Do normal girls read yaoi?
My bad, i'm sorry. It looked like you were saying what that first guy had said to the OP. Putting that aside, you had said they were calling the girl gross for reading yaoi? It looked more like they said she is gross for calling herself a "normal girl". It seemed like they thought she was interchanging straight with "normal", but it seems to me that when she said "normal" she meant that she isn't into bestiality. I think they thought she was saying "so i'm normal (straight), but i thought that scene was funny", they brought up that she reads yaoi because they thought she was implying that "normal" people wouldn't find that scene funny?
I'm but a normal girl who laughed when I read the words "How splendid that you're into beastiality" (づ ̄ ³ ̄)づ
