you are the one that replied to this commenter's comment in the first place. don't start things if you don't want people to finish them. do what you want man, i'm not your mom. it is genuinely just honest feedback, an innocent remark, not an attack on your manhood.
No one else finishes things other than me. I start them and finish them, don't tell me what I can't do. I finish this conversation, this is over, stop replying. I've proven myself correct.
