Flags on Labour Day tells me the people don’t know the difference between Labour Day, which is in September, and Memorial Day, which is in May.

Memorial Day is not a day for celebration, it’s a day for paying respect to the ultimate sacrifice made by soldiers. Labour Day is about celebrating labour, i.e. workers. Of course most people do celebrate both days, especially if they have the day off of work, but grilling burgers on Memorial Day and knowing the meaning behind the day is not as egregious, IMO, as waving military flags on Labour Day. Just sounds like someone is confused or not educated.
