The other day I unsubscribed from a popular Javascript mailing list, after the writer switched from writing about Javascript to writing about how white people and black people should interact.
Or rather I didn't unsubscribe right away: I emailed the writer politely and mentioned how I prefer posts to be about the thing that unites us: Javascript.
Their response: "my platform, my voice", "all tech is political", "this mailing list isn't for you", and later on Twitter: people who unsubscribed are racist and should "eat shit".
I don't believe I'm racist. It's just that I signed up for Javascript tips and the writer switched to politics (in this case, the politics of a country and culture I don't live in).
I'm no more interested in their political views than they are in mine. On the internet, nobody needs to know I'm a dog.
