How does that make me incorrect?

Bikes models have different seat tube angles. Many people I see with saddles that have large amounts of setback are using their road bike as if it were a cruiser style bike. Cruiser will have less of an angle to between the seat post and horizontal so that effectively removes the need for more setback since the saddle will be further behind the BB than a typical road bike.

And as I said in my post, it's my belief. Not an absolute or that there aren't circumstances where it is warranted.
