The problem is that we’ve been brainwashed by popular thought to the point we don’t even recognize a goyishe idea. This is one of the (many) terrible effects of golus. There is no comparison whatsoever between a Torah given Yom Kippur and some “mother’s day” (which to us Yidden is everyday) initiated by some drunkard in Congress or wherever that doesn’t understand one iota of Kibud Av V’Eim.
We have Kibud Av V’Eim. We focus on this fully and completely everyday — it is one of the cardinal laws of Judaism and part of the Aseres HaDibros. They have “mother’s day.” When you have a “mother’s day”, every other day of the year is an excuse to kick your mother to the curb. Uch un vay, nebech, for the nochrim.
