Faster than light travel is not as impossible as adding two plus two and getting three, but it's more impossible than almost everything else a normal person thinks of as being impossible.
Her glazing-over of the causality paradox is also seriously weak. She's playing with language and spaceship directions instead of applying the least-convenient-possible-world principle to her argument. Instead of her two spaceships going two directions, how about a single one going in a circle faster than light? Like I get it, I hate it too, but you can't just dismiss it like that.

That's constant acceleration, which doesn't add anything to the situation besides more things to keep track of and thus be confused by.
