I happen to think that reform is not a viable option. Reform is NOT the same thing as becoming MO and wearing a blue shirt and getting an accounting degree or whatever, just examples of a viable frum life one can lead outside the yeshivish and chasidish communities.
Reform is not one degree less frum than MO. There are huge differences (some of which have been blurred by OO) but someone who leaves the frum community and joins reform might not even have Jewish children.
I do think many parents would disown a child who became reform, but not one who made minor changes in their derech. And FYI I grew up chasidish, and where I grew up these minor changes would not be grounds for disowning a child. It would be grounds for the neighbors to yenta, though.
