Yep, absolutely. I think anybody who laughs at that is not quite appreciating what's going on and what makes Leatherface tick (or not tick, in the movie's case).
Leatherface is an imbecile. He does what he does not out of aggression or evil, he's just doing what he thinks the rest of his 'family' expect him to do. And that makes him ten times scarier than someone acting out of malice. With Leatherface, it's impossible to reason with him. And that's the scariest type of monster.
