You have a right to speak to those who choose to hear you (to wit: not be punished for doing so). That is the point of the ruling in question: Citizens United made a film (acknowledged by the court as none other than a 90 minute campaign commercial directed at a particular candidate) and accepted money to "speak" (via pay-per-view, prepaid by corporate supporters) to those who made a deliberate and positive effort to listen; current law forbade them from doing so, and there was no other way to allow it while preserving the bulk of the abridging law without instilling a "chilling effect" on other lawful political speech (which would be deemed so by voluminous case-by-case analysis, there being no bright line).
