that wouldn't necessarily be revolutionary in that case, be more anarchist
if that were the case, that the window wasn't secured down, or bricked up, it would be best to ask the person nearest the window to open it... if the person nearest the window was at all decent that person would do so... otherwise you would have to get up and open it yourself
but in this metaphor, as applied to the way the world actually is, the window is blocked by a bunch of bullies that won't allow you to open it
you have to struggle with them first to get to the window
what is revolutionary is to get the whole class to stand up with you and take the window, you have to make them aware that we can all be cooled down, but we have to open the window, and we need to overpower the bullies, then we can take control over the window and have much better conditions
if it were just a case of opening the window, without all of that additional struggle, there wouldn't be a problem other than asking someone to open it or getting off of your ass and open it yourself
