I post this thought here in the "Media" forum because this is one issue that we can see is clearly steered by the major media.
It is mainstream media that tells us to get flowers and send cards, rather than the original message of Mother's day, which was to help mothers around the world avoid the grief of losing their sons to war.
Julia Ward Howe first proposed the idea of Mother's Day in her 1870 "Mother's Day Proclamation".
It was a call to disarm, an "anti-war"bit of activism from the late 19th C.
That message has not lost it's appeal and urgency after all these  years.
