he's actually right
"I absolutely agree with you OP. I feel that this type of response does not warrant any attention nor does it contribute anything to the discussion on hand. I hope that many others feel the same way."It won't hurt to write more than "I agree" and explain why, not targeting you at all, just saying.
Please stop. If you have nothing worthwhile to contribute to a discussion, and you are simply quoting someone else's post, don't even bother.
