The mod note was added on as a courtesy so that you would have a direct and immediate response. You are correct that it is a time when people need to be accepting and find good in each other but at the same time we are not halachically permitted to extend that kindness toward people who pull others away from Torah.
There may be people in the organization who want to help those who are already out, but the point of the organization is not to help you make peace with Torah. I agree that it is painful to hear people speak this way about other Jews but we cannot misplace our love and kindness to people bent on destroying Torah Judaism.
The comments have nothing to do with them being on a different level of observance, it is about their objectives.
