Limbaugh isn't telling his listeners what to think, he is telling them what he thinks. If someone decides to agree with his assessment, that doesn't make them a mind numbed robot.
This has never been my experience in listening to Limbaugh, but lets see.
From his website and the transcript of last Friday's show.
Thank You, Peter Slen of C-SPAN
The opening paragraph, and thus the opening comments, are:
RUSH: Let's go to C-SPAN. This is from this morning on Washington Journal, and the host is Peter Slen. He was talking about me. This is the most talked about show in the country, most talked about host in the media. And of all the things I said yesterday, this is what C-SPAN found curiously interesting enough to put out there and discuss.
First he made no comment about how important this story was. He immediately cited where the story was going to be taken from, who the host on C-SPAN was, and what he was talking about.
Then he quotes Slen:
SLEN: Rush Limbaugh spent a lot of his show on Thursday talking about this issue, and from the website, RushLimbaugh.com website, "Brian Williams Should Not Resign His Job as NBC Narrative Reader," is the headline. Here's a little bit of the transcript: "They're not news readers anymore. There certainly isn't journalism going on here. It's not just NBC. It's the whole Drive-By Media. They're narrative readers," Mr. Limbaugh said. "You know, in the UK they call 'em 'news readers.' You know, BBC, the news anchors, they're called 'presenters' and 'news readers.' Here they call themselves 'journalists,' and they give themselves awards for bravery and courage."
Then he gives his take on it:
RUSH: And you know what? I have to give credit to Peter Slen of C-SPAN. He actually went to my website to find out what I said, rather than rely on some liberal "watchdog" fraud website. So thank you, Mr. Slen. Thank you, C-SPAN.

Another example from the same day:
Obama Wants Your Retirement Account
RUSH: It's a story from the website Watchdog.org, and the headline: "Obama's Budget Targets Your Retirement Accounts." I can't recall the number of times that I have mentioned casually, forcefully, predicted directly over the course of the years that, as this government continued to expand and spend money it didn't have and print money it needed, that at some point it was gonna have to go get money.
He immediately cites the source and then comments on it. On the webpage he cites the sources for the story again.
President Obamas 2016 budget targets retirement accounts
President Obama?s 2016 budget targets retirement accounts - MarketWatch
Of course this is but two examples but in neither did he say "this is how you should think."
