This does not make them bad people, Heaven forbid. That is not the point. Moreover, these Jews are likely the ones who are spiritually inclined, devoted Jews, who if only their movement were more halachically appropriate would be living lives of significant Jewish accomplishment. See how the movement has failed in its mission and how it tries to fool itself in trying to continue something that is neither Jewish nor effective. Of course there are many Jews in the world who are unprepared for a life of complete devotion to halacha, but all that means is that people should be patient, tolerant, and understanding, not that some folks should get up and attempt to change halacha to fit the already existing lifestyles of their constiuents.
Growth can only come if there is something to grow towards.
