That seems to be a very large mouthful of what you perceive as wrong in the Church; but let’s keep it to the topic at hand, the Eucharist.
Cookies of various shapes and sizes? What ever is that meant to be? There has been talk of other than wheaten hosts used on rare occasions, and I have yet to meet anyone who actually witnessed such an act and can name a time and parish.
If you are talking about the shape of legitimate hosts, then perhaps you should do a bit of research as to what throughout history has been their shape and size, as I suspect you are referring to the paper thin hosts of recent but pre-Vatican 2 times. Other than that, your charge seems specious; perhaps you can give date and time to your charge, and be more specific?
