That's a bummer honestly, I would encourage you not to let Internet flamewars color your decisions about what languages you might learn. The well is seriously poisoned with regards to Rust in this community. That's more of a reflection on HN than the value of Rust as a technology or even the Rust community.
Don't learn Rust if you aren't interested, it's not a one true language, but don't cheat yourself on engaging with an interest because HN struggles to discuss it amicably.
HN is capable of discussing it just fine. Low-effort, bad faith posts getting downvoted into oblivion is the system working as intended.

There are people who can operate motor vehicles safely at speeds regularly in excess of 100mph. People should not do so on public roads.
