Promos for PBS between programs

I am convinced I would send my local PBS station a membership donation if PBS would consider stopping those endlessly run PBS promos that must target fifteen year olds. They are loud, jarring, puerile in content and driven by the most obnoxious musical accompaniment. PBS broadcasts such great programs, only to diminish the viewing experience by forcing viewers to repeatedly watch these moronic promos. It makes no sense, unless your prime audience consists of hysterical adolescents. And your between program promos on Create? Have any of them been changed in twenty years? All those grape tomatoes? Brazil 66? Please help!
