Why do you say it is not Orthodox? The faculty are shomer mitzvot, with Orthodox semichah.
I don’t know enough about YCT to say much about them. However, the fact that they are shomrei mitzvot and have semicha from Orthodox institutions does not really prove much.
JTS’s faculty used to also be shomrei mitzvot, and had Orthodox semicha, and even included such scholars as Saul Lieberman. Yet- nobody debates that they were clearly not Orthodox, and clearly did not represent Judaism.
