Protect pedophiles, but not pregnant women?

I'm sure I must be missing some subtle nuance here, but last week a congressional committee blocked an amendment to the Local Law Enforcement Hate Crimes Prevention Act (HR 1913) which would have broadened the protected classes under the bill to include pregnant women.
The same committee then blocked an amendment which would have defined "sexual orientation" under the protected classes in such a way as to specifically exclude pedophilia. (committee vote here)
So the end result is that the committee determined that pedophiles should be protected under hate crimes law, but expectant mothers should not.
