I think he's right though. You didn't specify that your problem was with the quality of his threads in your first post, instead you said that he shouldn't have made a thread about this subject entirely. You changed your argument with the second post, and he called you out on that. It's that simple.
Don't get me wrong I'm not saying that he shouldn't consider your feedback, this thread is quite poor on content for sure, but there are ways and ways to go about it. Try to be more welcoming mate,
I have faith in you.
