Farshteit zich that my previous comment was speaking in broad terms rather than individually to TM. That said, TM self-identifies as MO/DL, and as mentioned MO/DL in the broad sense is the left-wing flank of frum Judaism (which is the only Judaism.) This, of course, discounts OO since a) OO self-identifies as MO and more importantly b) the rest of Orthodoxy (including the rest of MO) considers OO to be non-Orthodox/non-frum, much in the same way Reform “Judaism” is not considered to be Judaism by Orthodoxy and J4J is not considered to be Jews or Judaism by all Jews, despite both of them claiming the mantle of the name Judaism.
Now within MO you have the so-called LWMO and the RWMO. But LWMO is virtually synonymous with OO, which the description in the previous paragraph applies to. That all being said, broadly speaking MO/DL is as far left you can go within Judaism and still be said to be frum. Within MO, individually of course, there are certainly some more to the left and others less to the left.
