I’ll engage back and forth a total of three times, if I choose to engage and depending on the comment. I blocked one person who said my work showed that I was unhinged and victimizing my family and that I need to stop making things up. I also made two comments to the person who said my memoir piece didn’t happen because the dialogue wasn’t real (it was, the best I can remember). In my first comment I suggested that they might not understand what creative nonfiction is, and they said “yeah, it’s not that…” and I then said that there are lots of excellent writers on Medium and they may enjoy some of those stories. This person is purposely anonymous and the reason I’m good at dialogue is that my professors in graduate school told me I needed to work on it. So yes there are different ways to approach comments depending on the nature of them.
