Really? The first thought they had was fuck NASA and they completely ignored the trillions being spent on the US military complex?

I'm not sure why you are forcing a choice between the two. People can be against spending on both NASA and the military. Also NASA isn't completely separate from the military industrial complex.

This is a false dichotomy.

I think he's using the false dichotomy to point out that there's a hell of a lot of other bigger, less popular things than NASA that jump to mind if one's goal is to free up resources for solving more local problems.

I was mocking a false dichotomy... Covid crisis -> we have to cut space funding.

I wasn't even presenting a dichotomy let alone a false one. There have been a number of issues that have shown an increased urgency over the last several months, not just COVID. As those other issues become more urgent, space exploration falls further and further down many people's list of priorities for funding.
