Am i an asshole for this?

so i'm in the xbox live party with some friends. when one of them starts reading an article on ign about mass effect 3. now i'm syked for it. but i don't wanna read anything on because they might throw a spoiler my way. so he reads it and he says sheppard starts off in court. then he says liara breaks you. so i'm like dude if your gonna blurt that **** out can you mute me. he goes on like why. then my other friend blurts something else out and i'm getting pissed. i ask if they can mute me if they talk about then they both throw a fit. then one says that the liara thing was a lie. he didnt say "i think"or"what if liara break you out" no he said it as if it was gonna happen. he did this **** with naruto. the new chapter came out and 2 of of them read it. i said don't tell me i wanna find out. one of them muted me and the other didn't so i hear him repeating everything the guys telling him "OH SO NEJI SO AND SO" am i the asshole for getting mad? yes no
