I wouldn't worry about it so much with clothes because we don't expect them to last generations like we do quilts.
ARRRGGGHH how long will this myth prevail? This is not true, a fabrication a falsehood, been debunked. Poly thread will NOT cut through your cotton fabric over time.

And if you don't want to go to the above link here is a direct quote from Dr. Bob of Superior threads
The point is this: The traditions, myths, and rumors that polyester thread will tear the quilt are not true. Under extreme use, a strong polyester thread might, but so will a strong, glazed cotton thread. Under normal use, softer non-glazed threads will not tear through the fabric and it is perfectly fine to use any type of quality thread, except nylon. Nylon will go brittle and discolor over time. Choose your threads based on quality, feel, and appearance, avoiding wiry glazed threads. Although they are rarely labeled as such, if the thread is stiff and wiry, it most likely has a glaze coating.
