Yes, because they are the press. But a corporation which pays for the press to run advertisements is not the press.
Please explain how the above lines up with your idea that corporate entities cannot exercise rights? You've now agreed that some, in fact, can, but only certain ones. Who decides what constitutes "legitimate" press? And if we do something like that, does that mean that, say, a BP can go out and buy an outfit like the NYT and spout all the pro-BP propaganda they want to, since they're "the press" now, too? Can the Republican party buy Fox News and run thinly veiled political advertisements disguised as news? (I really, really want to make a joke here, but, sadly, the right one just isn't springing to mind).
Lastly, does that mean if I can't afford to buy the NYT, or Fox News, I simply don't have access to the press?
How many cigarette ads do you see on TV? Have you argued that RJR's free speech rights have been violated?
FWIW, I think smoking is a horrible habit and a downright idiotic thing to do, but personally, I do NOT support the ban on advertising that is becoming more and more pervasive as time goes by (it started with TV, it's spread to other media). I think that neo-nazis, KKK, and their ilk of other races who preach the same kind of hate are the scum of the earth, but I don't support muzzling them, either--hate speech is still speech. IOW, I disagree with what you have to say, but I will defend to the death your right to say it.
Does a corporation also get the right to vote? I have an LLC with no income, can it apply for food stamps under the "equal protection" clause?
You're reaching on this one. Please note, I am NOT advocating the "corporations are people" line. I am advocating that people acting in groups have the same rights as the individuals that compose them. You don't get an extra vote because you incorporated, you have as many votes as you have members. I'm not going to dignify the "food stamps" thing with a response.
