Lacan is practically the king of bullshit-- a textbook example. No one can muster a non-bullshit explanation of what exactly the fuck Lacan is talking about (I'm looking at you, Zizek, bless your heart).
In my experience, most people who are "suspicious" of Freudian psychoanalysis don't understand how psychoanalysis began and evolved over time, and they don't understand that some of it's stranger jargon refers in fact to very straightforward concepts. It's true that Freudian analysts have overreached and been wrong in various ways, but you're incorrect and you're throwing the baby out with the bath water if you think that somehow invalidates all of the revolutionary and important work that Sigmund/Anna did.
