Colloquial use of that word is not related to its technical use to describe a female dog in dog breeding. Colloquial use of the word is precisely driven by misogyny. Don't try to play that game, it's dishonest. Do you think the homophobic f-slur is acceptable because, after all, it is a technical term relating to bound wood fuel? If not, why is that not acceptable, but the one you're using is? Historical linguistic justification for a word whose colloquial use has not been related to its historical meaning for a very long time is dishonest.
By "otherwise discriminatory" I meant discriminatory in ways other than the two (sexism, ableism) that I explicitly mentioned; can you not think of other ways to discriminate? "Otherwise discriminatory" can include words that are specificaly xenophobic or racist, or homophobic. I didn't bother doing a full inventory when I was illustrating a point.
I find casual use of opaque blocklists without any second thought to their impact disturbing.
It's not opaque. The entire block list regex is publicly visible for every single instance. In fact, it's in the page source of every single page you load. You're simply uninformed. Moreover, if you think there was no second thought to it's impact, you're yet again uninformed. There was (and has been) discussion about it amongst developers and (early) users, and discussion continues; in fact, there was a post about it with large engagement maybe three days ago.
I am not sure how I feel about enforcing a block list (and I said that in my previous comment), but one thing it does do, repeatedly, is illuminate how little people think about offensive things they say. Interestingly, more often than not, people would rather defend their use of misogynist language than consider using literally any other word in English or another language.
You must have the distinct privilege of not living in the USA or several other Western countries.
If you mean jump ship off that ISP, there's nothing you can do. You can go to another ISP (if there even is one in your area), who will do the exact same thing. You can jump ship entirely and not have internet, I guess.
