I agree with all of these points, strenuously. Everyone should have this information, and believe it. The next segment, however, involves "Stop Signs - phrases or actions that should stop a sexual encounter." One of these is "I guess, if you really want me to," in a tone that suggests coercion. I have some trouble with this. While I understand that it can be hard to vocalize a "no," no one should expect a partner to guess that we mean something other than we're saying. Just as "no" doesn't secretly mean "yes," the opposite is also true. That said, looking out for vague or unsure language is good thing to keep in mind when you're dealing with other people who may not be so forthcoming.
The last segment covers situations where consent can never be given, even with a verbal "yes." It's excellent information that includes being drunk, being underage, or one person having authority over another. If you've never taken a look at the vids of Laci Green, I highly recommend her. She's engaging, cute, and chock full of great information.
