the comment you are harping on was about the one day boycott...

this conversation has morphed since then but he was late to the post and even mentioned the later replies in his post in contrast to what you are are trying to correct him about

also...he's right in general...what people don't buy in/on one day...they will buy another...

it's been suggested that those days be pushed back to Black history month so...even if you take issue with that premise...it's a great chance that he's correct on it as well
