the hounch joint

In an earlier post: 19th Jan 07, bill Sutton claimed:  I don't think there is any significant structural advantage provided by a haunch; in fact I think it could be argued that it may actually weaken the post.
Can we take it: the Post, to mean a stile. (English termination)
Well to me? either way that is bad advice.
For on a chair leg/rail joints for example, the haunch is there to? Stop the top end, of a (if Used) Ordinary mortise joint twisting, inward or outward? Causing the glue joint to fail thus needs a repair,
. By including a ¼” long haunch on the tennon, the mortise & tennon joint is connected the full width of the rail, at the joint line /same at the mortise. Making a joint that can never twist out of alignment.
The same rule applies: with a house door, a window frame, paneling, or furniture.
Remember: Haunch joints are there for a purpose, to make a stronger joint.
