“Just a member: JTS isn’t like that anymore. I said it used to be fairly observant, maybe even the MO of its time. But those days are over… YCT purposefully tries to be creative within the halachic framework- they actually cite mekoros and learn Gemara. They might be wrong but they at least try.”
yct is on the same beaten path as jts. jts, also, gives a “creative” halachic framework with a “psak” citing mekoros, just as you say yct does.
