I don't know moo... maybe things for me and you work in a different way, but Valentine's Day is not to be taken that seriously, negatively or positively, it's the same. People who are alone are free to ignore it. I don't think someone who has not a significant other for a reason or another could be bothered by it. Also if you have lost somebody, Valentine's Day is not that great reminder. The ones who are with another person can either ignore it or just consider it a special occasion. I doubt anybody who's really seriously involved in a relationship can consider Valentine's Day as the ultimate occasion to show love or appreciation to someone else. So... I don't think it has to be banned
