How can I not use the Facebook for HTC Sense on my HTC Incredible?

I'm trying to add my Facebook account instead of using Facebook for HTC Sense. However, when I go to Accounts & sync > Add account > Facebook, nothing happens. If I tap any other account, I get prompted for login information (or, if I'm already logged in, the ability to change settings or add a second account). I really dislike the Facebook for HTC Sense, so there's got to be a way to add my Facebook account without using Facebook for HTC Sense.
