first you asked me if i read a misguided hand wave at "freedom of speech is out of control" opinion piece, now you're asking me which particular freedoms are "lost" if a specific case is overturned? i'm sorry, but that isn't serious. if you have a thesis or something, go ahead. please note context.
i'm not trying to be difficult or dismissive. it's like you're asking me "why is freedom of speech important?" or "what happens to the country in 10 years if the supreme court rules this way or that way on this case?" neither of these are "stranger on microblogging site" questions...
Non-profits, labor unions, and corporations would lose their right to engage in political speech 60 days before an election or 30 days before a primary.
The Citizens United decision surprised me: I expected 9-0, not 5-4. Political speech is core to the 1A.
