An ad hominem if I have ever seen one! To answer your question though, yes as it gives a simple, researched and concise explanation as to why these are useful and might make the commenter think that they aren't as "meaningless" as they seem.

I am not sure why you interpreted my comment as an ad hominem but I sincerely apologize for offending you, that was not my intention.
