Why organize?

definitely not a fag, but this concept has certainly been troubling me recently.

This is the best answer so far. So Marx analyzed historical trends to discover the historical cycles communism is based on, identified proletariat and bourgeoisie as the two classes in conflict in our time, and devised the system necessary to move humanity forwards? Thank you that makes lots of sense.

If you eventually get over a cold or the flu, why rest or take medicine?

This is actually close to the Leftcom line of thought. Lenin addressed that sort of thinking here and here marxists.org/archive/lenin/works/1920/lwc/

As Slavoj Zizek says, "communists experience themselves as instruments in which to exercise a historical necessity"

This was more of a development in the 1910's, but anyway the point is that this theory isn't meant to be disconnected from your actual action or day-to-day life. You're living in it.

people throw logs on the fire when they get cold

ok then go read a little into the founding of the IWW including its constitution-charter

I wouldn't put it exactly like that but close enough. Someone else mentioned leftcom which also took a different line towards political organizing than the socdem-bolshevik one. Anyway if you are a burger definitely look into the IWW (historically not like getting involved nowadays)

Capitalism will collapse, yes, but socialism is not guaranteed. Fascism is the bourgeois solution to the contradictions of capitalism. If we want socialism, we need to work towards building it, and fighting the growth of reactionary movements.

Socialism or barbarism.

Guys who have read Marx extensively please correct me if I'm wrong but afaik Marx never said the revolution (and therefore socialism and communism) was inevitable. He simply said that it was one of the possible ways history could end. Obviously that would be the best option but it's still possible that that's not what'll happen and capitalism ends up wiping us out in the near future. Or nuclear war or climate change, shit like that. That's why we shouldn't take communism for granted as in it'll inevitably happen some day.

Whether or not you agree with every point, this answers pretty concisely.
