Anonymity is a broad term though. I would be incredibly surprised (and fascinated) if anyone on HN can find my true identity from my account, even with an e-mail address in my profile. I also know that Google (and therefore powerful bad actors or law enforcement) can easily figure it out, since I've logged in to this e-mail address from the same devices as my private e-mail address.

If I'd need full privacy, I'd have to add many more levels of security in my daily life that I don't find necessary. I just don't want people (or a SWAT team) to show up at my door because I triggered someone on the internet. That's why I post from multiple different accounts on different platforms. Though, I'm sure, in the future some form of AI will be able to link them all based on writing style and similarity of content of my posts. Guess I'll have to find another way to remain somewhat anonymous then.
