a) That’s a fair way to describe it regardless of political leanings, and moreover even if it wasn’t, I fail to see how that’s somehow able to be extrapolated to the entire org.
b) Last I checked government employees are allowed to express their opinions, which would be relevant had the man not resigned - meaning what you’ve read is a personal take. Like the vast majority of people, I doubt he took politics to work.
c) Consider 18F was started under the Obama administration and continued through the first Trump administration.
The federal government is being actively dismantled right now in ways that are unprecedented - even for every Republican administration in recent history.
I think it’s reasonable to say “far-right” isn’t partisan in that context. It’s accurate.
To use an example from the other end, it’s not particularly partisan to claim that a communist is on the far left of the political spectrum.
If a neutral observer calls you a fascist, it doesn't necessarily mean that they're biased or compromised. You might just be a fucking fascist.
