I saw the same post and started writing something that went in a different direction, but that seems complementary. Basically, you don't have to respond.
I do believe you're responsible for what you write, but you're under no obligation to answer any and every kind of criticism that is thrown at you. You might have to read something that's hard or hurtful in the comments, which is fine if they are trying to follow the recommendations listed above, it's a process, but you don't have to accept an attack to your personhood or an attack to what you wrote without any explanation.
I understand the desire to make clarifications and being clearly comprehended, or defending oneself from attacks, but a direct response might be counterproductive. Say nothing, or go back and put amends to the original thoughts with an edit.
Also, and this is for all the parts involved, the discussion is not going anywhere. It will not get drown out in a sea of comments, you can take your time and come back later. More importantly, you'll likely see the same people around again. Take care of your community. Defend, understand, educate, be nice.
