I hear you, in a system where votes are distributed equally and where a duopoly isn’t an eventuality, you’re absolutely supposed to vote for the party you allign most with. The current system does not permit this, causing a black and white world of politics. Not participating in this is your right, and with two regular candidates, we’d probably never have this conversation.
One party has the rationality to change its opinion and work on mutually beneficial solutions, and the other party polarises the population, advocates for violence and creates lies and deceptions at every corner.
Firstly, this is for creating concrete on mars, where resources are very scarce and making regular concrete is not viable. Secondly, to survive martian conditions, we need to build bases, a lot of very sturdy, structurally sound bases. And lastly, before the potato based concrete, blood was genuinely the most viable solution, being an easily renewable resource. IIRC the martian concrete is now magnitudes better than regular concrete.
