Do atheists like holidays?

Some atheists sometimes talk about not wanting religion around. Even if you don't believe in God you have to admit that the world would suck without him. No christianity no Easter or Christmas. Even Halloween was a religious holiday by the druids. So without religion the biggest holidays you'd have would be Thanksgiving or Valentines Day. Also Mother's Day, Father's Day, and Fourth of July. So would it be worth giving up religion if you could never have Christmas or Halloween or Easter again?
