Seems like Kling is a wee bit of a chud. The claim about human rights likely stems from the "trans rights are human rights" mantra and is likely is reference to this (https://github.com/SerenityOS/serenity/pull/6814) where Kling accused a contributor of bringing "personal politics" to the project for changing one instance of "he" to "they" in a markdown file. Since then he has, for example, apparently gone on to complain about anti-white discrimination in the workplace (https://x.com/awesomekling/status/1874518295350837401).

For what it's worth, the perpetually-offended progressive has become an annoying stock character in our culture. At risk of falling for Poe's Law, the commentor on that PR who said "The denial of non-male users and/or developers is sufficient reason to not use SerenityOS" is a perfect example of this. Another more contemporary example would be the seething outrage over Last Ditch Bar's new mask-optional Saturdays.

Ladybird have a "no politics" stance by the looks of things, what that really means is kind of up to you. Here's an article about it further, I'm biased against it and so is this article so take that as you will:

Also I'm seeing comments suggesting that the lead behind it, Andreas Kling, is quite openly on the DHH side of things

Something weird happened with this comment. Someone throws a baseless accusation, I then go and research the issue. I link to the sources that I find, the comment gets 3 points.

The next day, it's already at -1. I've been observing this for quite some time.

Can you give some examples of these "extreme far right" beliefs, by which I assume you must mean beliefs that are so extreme that something like only 1% of the most right wing parts of the population could believe them?
