Avenged Sevenfold frontman M. Shadows made a huge mistake last night (November 7): He shared an opinion on Twitter that an intense fanbase thought was an attack on them, and then they got all up in his mentions.

That intense fanbase? Swifties aka: Taylor Swift fans. Just a quick lesson for everyone on things you shouldn’t ever do:

-Don’t tug on Superman’s cape.
-Don’t spit into the wind.
-Don’t pull the mask off that old Lone Ranger
-And don’t mess around with the fanbases of massive pop stars!

Anyway, here’s what went down.
