Anonymity can enable that but it also enables far nastier things. There are pros and cons. Simply pointing out pros is not enough to win the day.
my favorite part about non-anonymous accounts is being able to find their employer if they say something that's annoying.
An excellent (sarcasm registered and understood, BTW) point.
I am a practitioner of BDSM[0], which is, in some circles, quite controversial.
Despite the fact that my activities are always consensual and never cause harm to anyone, if my employer, clients or others with whom I have unrelated interactions with had negative ideas about such things, I could suffer serious repercussions.
I generally don't discuss such things online (or offline, if those I'm around aren't trusted), but if I did (as I am now), forcing me to link those discussions with my "legal" identity, could inflict real damage on my life -- even though nothing that I do is illegal or harmful.
As such, Vangelis is 100% correct. My private activities, unrelated to my work, are none of my employer's (or anyone else's) business, nor is it a danger/threat to anyone. If I didn't have the veil of pseudonymity here, I would never even hint at it.
And that's the problem with de-anonymization.
