Ok, so you think SASEs are only for rejections.
You think they are a waste of time.
You think if I want your book I'll contact you.
I'm not going to spend much time trying to convince you otherwise.
I'll leave it at this: if you don't include an SASE in your query, I'm not going to read it.
I'll tell you this ahead of time, not as some sort of idle threat to follow the directions or die, just as a heads up.
There's a lot of advice out there on the internet about how to send queries.
I'm the one reading the slush pile.
