The COfee Room is really a unique place in that it actually allows a no holds barred conversation that actually lead to people learning things they did'nt no before and relearning things they think they knew.
Talmud Torah K'neged Kulam does not refer to the fact that through Talmud Torah one can be mekayim the entire Torah.
The above statement is true but not what the aforementioned Mishna is referring to.
The mishna is stating a simple fact that the LEarning of Torah is equal (Kneged" "all of them" all Mitzvos.
The Vilna Gaon actually says an interesting thought based on that.
The Gaon states that each word of Torah is equal to all 613 mitzvos.
On Shabbos the Gaon writes each mitzva one does earns schar times 613 hence each word of Torah that one learns is 613 times 613.
Pretty interesting, No?

For a clear explanation on the vast differences between the two complete with a myriad of clear and outright demonstrations of the aforementioned differences, please see Rabbi Joseph Eliase's brilliant and comprehensive commentary on The Nineteen Letters.
And look Torah Judaisim has not changed their Hashkofas a bit, as evidenced by the fact that on this whole thread specific examples have been given of MO "changing" (thats being charitable) of Torah Law while not one single example can be given of Torah Judaisim changing Torah Law ch'v.
And yes if you hold beliefs and have a sense of priorites that are not in line with the millenia old tradition of Torah Judaisim.
Beliefs that go against Hlacha then Torah Jews will state that is Kefira.
