I'm sympathetic to hostility towards many members of the Rust development community, many of whom are left-progressives who think it's politically and morally important to exclude and socially-punish people who they view as being insufficiently deferential towards communities they deem marginalized.

But Rust is actually a better language than C, in multiple ways; and it is in fact bad that so much software in common use is still written in C. C is extremely hard to write correctly and hard to maintain; this fact explains a huge amount of security vulnerabilities in the widely-used software written in C. Rust mitigates this to a large extent, and is also just more pleasant to write because it has better syntactic and semantic affordances than C does - also better developer tooling.

I think that people who are not Anglophone left-progressives should use Rust, in part because I think it is bad that a highly useful programming language is associated with Anglophone left-progressives. Certainly, regardless of one's non-programming-related political beliefs, you should not ground your identity in making a virtue out of sticking to C.
