Agreed with the sentiments expressed. There is a time and a place for a bit of banter but this is not it.
I have only previously had a vague understanding of memorial day and so read the Wiki entry. Staggered to read that over 600.000 died in the Civil War, more than 10 times the number who were killed in Vietnam. No wonder that the shadow of that bloodbath is still evident in the US
I hope that those who are mourning a family member find time for quiet reflection away from the barbecues and drinking that the OP describes
