The "Red-pill" in the Matrix signifies an action which one cannot go back on. It is an action which requires the user to shatter their built-up version of reality forever (signified by the the blue-pills they have been taking all along).

We need more people to challenge their view of reality, and accept that things may not be as happy and comfortable as we want them to be for the security of our futures and our children's futures.

And no, I don't mean "global warming is destroying the ability for life to live" wise, I mean in terms of how much our politicians and public servants are truly serving us at this point. Voting for lifelong politicians more or less got us here, the red pill is accepting that these people may have always had more sinister plans in mind than we thought.
