You've gone straight for the straw man of somehow seeing a "requirement" to kneel, that has never been there.  I have never heard of anyone being chastised for not kneeling when the instruction calls for kneeling.  I have, however, heard of people being chastised, even publicly, by a bishop or priest, for deciding to exercise their right to kneel to receive our Lord in Holy Communion.   Requiring a person who desires to kneel to reverence our Lord's Eucharistic Presence to stand as a condition for the reception of Holy Communion is not merciful, and it is truly dangerous for the eternal souls of the bishops and priests who have done this.
