How come you disabled comments for your new videos? Or do they not work because they are all video responses to other reptile videos? Also, you shouldn't let one hater bother you.
Comments have never been disabled. I talked to someone off the public forum the other day and apparently YouTube has been having issues with there servers that run the comments so that may have caused issues on the videos lately. If this happens just click on "See all comments" and you can leave a comment there but the past couple videos seem to not have an issue. I am not sure what you mean about haters, I went and re watched the link and I have no idea.
