No, you're not. I was robbed, and so was the other person. Same thing could happen to anyone in the cryptocurrency world.
So you are saying you use Coinbase and your Coinbase balance went down after you received Bitcoin funds? And there is a transaction in Coinbase history that shows a BTC withdrawal ("You sent bitcoins to xxxxxxxxxxxxxxxxx") and you did not make that withdrawal request? And that you have 2FA authentication?
Well, then let's consider what could have happened.
Authy is the 2FA authentication method that Coinbase uses. Authy requires a mobile app or alternatively the 2FA code for withdrawal is sent as a text message.
So did you receive a text message with a 2FA code from Authy?
Either way, Coinbase can help you figure out exactly when this 2FA code for this transaction was sent (and Authy knows the the IP of the mobile device if the 2FA came from an app), and the IP address that was used when accessing Coinbase.com for that withdrawal transaction .
Have you contacted them?

I hadn't quite received my funds. I believe the The 6th confirmation had come, but the status said something like "Just a minute until confirmed". It did clearly say the receipt of the coins was pending when to order to send them to another account was also pending. I never saw my account balance above 0.
I did receive a text message to my phone with my validation code when I logged in, but didn't receive one any other time.
I've contacted Coinbase via the link you posted yesterday afternoon. I haven't heard anything back.
