Re: most "wrong" episode...
Not interfering in another culture's development is all well and good, but what does that even mean? The Federation has ambassadors and alliances with various alien races. Shouldn't they cut off all diplomatic ties and go all crazy isolationists similar to the Vorlons?
No, because there's a difference between normal diplomatic contact and interference
