It's sad that you think your priorities should be everyones' priorities. Find like-minded people and get to work. But what people get inspired of is none of your business to judge.

I feel perfectly entitled to judge those who spend their days dreaming of Mars as a solution to their problems.

I will not support such efforts, and I feel quite comfortable being a detractor as well.

Who are you to tell me what to judge?! This argument gets you nowhere with me.

They aren't dreaming of Mars as a solution to their problems.

They dream of Mars as it is exciting and will lead to new knowledge, understanding, and meaning.
