Can you destroy enchantment creatures?

Only the enchantment is destroyed as Tear makes no mention of destroying the creature it is attached to. However, if you had played the Hopeful without bestowing it,then targeted it with Tear , the Hopeful would have died as it is still an Enchantment type. TL;DR: Tear can only destroy Enchanments.

How does Enchantment creatures work?

While it's enchanting a creature, an Aura with bestow grants the creature the bonuses listed in its text box. If the creature it's enchanting leaves the battlefield for any reason, the Aura immediately becomes an enchantment creature again rather than being put in the graveyard like other Auras.
