I didn't argue that it's "tremendously different". I agreed that typical Western art music generally has pretty simple rhythms, and that other musical cultures often have much more complex ones. I said explicitly that time signatures in Bach are all 2s and 3s. But what you actually said was, in so many words, "every Bach piece, and every similar piece from other composers, is written in 3/4 or 4/4 time". And that simply isn't true.
