Misinformation. Do more research.
While (I think) I agree with you on the facts here, I don't think this type of dismissive comments are that useful either.
Can you give the replyee some pointers, for example? Link to articles or studies that show a different view?
Hi, Mr. wolf language.
If you have useful information to share, please do so. Telling people "Do more research" adds nothing to the conversation.
