Isn't saying mothers should get a day just the same as saying everyone is a winner?
I see what you're getting at - that it's potentially saying (indiscriminately of what kind of Mother you are), all Mothers are winners today! But it's not really like that because ALL Mothers don't get cards or flowers, just the one's that are appreciated by someone. So going by the analogy (if i'm using that word correctly??!) some Mothers will win today and some will lose 
I used to ignore the day for myself, thinking it was just a money spinning thing, but I'm coming round to enjoying the national focus (albeit for one paltry day) on a role that is severely undermined and undervalued for the rest of the year.
Happy Bless the Mothers Day
