It’s a Google Chrome extension. Looking at the source, it’s not bad for a first time. (I would have used
replacement || match instead of the ternary operator, and that big block of replaces could probably have been done some other way but I’m not regexy enough to figure out how.)
I’ve never liked re-gendering; often it ends up sounding like a threat, but this line is just gold:
the matriarchy also hurts women
I don’t know whether to agree or laugh mockingly.
Edit: It’s also on GitHub and I know enough about Firefox extension development to never do so (three days just to get Hello, World to install!). Anybody?
