Imagine you have a laser gun. The lasers you can shoot with it are as fast as light itself. Your hand, however, still moves at human speed. Similar case with the Pacifistas. They shoot light beams, but they don't become it.

On top of that, the Straw Hats dodged their beams before, so nothing special really.
