I’m pretty sure that when OP said “biology is not binary” they meant “biology does not mean that you are either 100% male or 100% female” (true) as opposed to “people with Z chromosomes exist” (false)

If you want to quickly find RSS feeds without having to view source:

Want My RSS for Firefox

openfeeds for Qutebrowser

Apparently Google has an RSS extension but I haven’t looked into it.

Some RSS tools that are useful:

RSS Bridge

Kill the Newsletter

MoRSS (worked for like, one niche website I look at, but still might be useful)

EDIT: By the way, Facebook has been working very hard to fight RSS at every corner, but most other platforms still support it.

Also, if you use Kontact like I do, it supports RSS feeds through Akregator
