Why would you use something like PGP if you have to send your encryption key unencrypted to the party you are sending to? And if you leave this key out on something like Twitter for example, couldn’t law enforcement or a third party if they gained access to the other persons email still read the contents of the encrypted email by using this key? Doesn’t this defeate the purpose of using encryption?

The public key of asymetrical encryption is, well, public, its not a secret, you can share it with anyone or post it on facebook.
All others can do with that key is validating that a message was written by you(or whoever holds the private key to that public key) or encrypt mesaages with it that only the private key can decrypt.
