I watched a fairly heated debate between this guy and a friend of mine which resulted in my friend saying "I'm really not convinced that's going to happen".

To which I asked another friend, "what's not gonna happen?"
...
"Alien invasion", he said.

I guess I should also say that I had a very energetic debate myself with a friend on how to engage the apathetic, disillusioned, disengaged and largely poor/working class section of our population.  I talked about how the left wing narrative is failing to overcome the dominant right wing narrative right now.  He doesn't even think there is a left wing narrative (he's a radical lefty green type).  He reckons that none of the political parties really represent people outside the Daily Mail reading/corporate types bracket (Can't disagree too much) but nor am I convinced that we can just set up our own movement from the ground (cue all those apathetic yet still 'me, me, me' people with no critical thinking skills) to battle it out with the three main players...
