Your claim is wholly and utterly false. Reform Jews alright, they may all not keep kosher or shomer Shabbat, or have bended rules with regards to conversion and the who is a Jew concept. Yet, they vehemently do not believe in JC at all. Same as Conservative. They adhere to Jewish culture, philosophy and religion. Alright, no they're not as observant generally as someone who is Orthodox, but their care is for Jews and Judaism. They work with Jewish law as they understand it, so no of course someone Orthodox wont agree to driving on Shabbat or accepting the child of a Jewish father and non Jewish mother as Jewish but they still look into and work with the same texts and history as the Orthodox do, to different degrees.
