The Supreme Court has declared that corporations have many of the same rights as individuals.
Assuming you are referring to Citizens United, that is not what the court decided.
The court decided that individuals have the right to both peaceably assembly and freedom of speech. In particular, it's not an XOR - the government can't say "because you have peaceably assembled (in corporate or other form), you can no longer speak freely."
Citizens United was solely about the right of individuals to speak, and to use their property (corporations) for speech, as well as the right of other individuals to hear all ideas.
