You are the one who is claiming that they've saved $1.82 Billion dolars by posting some random website that thinks illegally destroying a federal agency is fiscally responsible.
You can and should talk about the biological and social origins of homosexuality if it interests you. But, you should avoid doing it in a way that's insulting.
I would also suggest, since it's a sensitive topic affecting people that have been persecuted, making sure the comments are thoughtful and non-reductionist.
For people who'd prefer to be cavalier about the subject though, there's not lack of spaces on the internet to do so.
I'd love more tools for using TeX and markdown. There are a few but they're not really given as a first choice anywhere.
About MathML... I mean I'm also not a fan. I'm not sure anyone really is. I've been cursed to work with it in some legacy pages. I love using mathjax. I'm not familiar at all with the two people who from the company who worked on it or that project. But I think it's going a bit far to think that MathML was nefarious corporate plot to manipulate the W3C. (0) MathML doesn't interoperate with WolframLanguage in any particularly great or exclusive way. (1) MathML makes more sense for the time period it was introduced than it does now. Mathjax is technology I don't think people foresaw at the time (Reparsing the DOM and injecting some kind of formatted math notation?!) People really thought math notation would need to be expressed in an XML like format. The other option at the time afaik was static images you'd generate from LaTeX and insert into your document. (2) TeX is a language for typesetting math in a paper and people thought we'd need something that went deeper, representing something closer to the intended semantics of the notation. This was probably a mistake.
Afaik MathML didn't make it harder for people to use TeX on the web.
So I feel like you're right in that we can do a better job of explaining how to do this (I obviously work at Wolfram Research).
But I think it's very possible and a strength of ours. Wolfram|Alpha is used by many services, including now MS Excel which I think is a counter example to the paradox you mentioned.
