Which of green day's songs are clean that is without swear words or hate messages PS I do not know a great deal about green day so please forgive me if green day's songs are all clean?

Good Riddance (Time of Your Life)

Know Your Enemy

21 Guns

Poprocks & Coke

Wake Me Up When September Ends

Whatsername

Those are just a few examples, and really about half their songs don't contain any swearing, anyway.
