Just as this issue is coming up here, one of the difficulties we are going to have to work with at our new forum is that there will be ZFI members who have strong negative feelings about E-sangha. There will be moderators as well.
We are going to start with similar terms of service as Dhamma Wheel, but this topic will come up. How to allow conversation and discussion and
criticism without stepping over boundaries into wrong speech, animosity and attachment to views?
I don't have an answer to that. We'll have to figure this out as we go along. For myself, personally, I am doing all I can to cultivate positive thoughts and feelings about E-sangha, the place where I met most of my closest online friends.
Sometimes people just need to vent. But if you take the time to reflect on "negative" life experiences there is usually a bit of dharma understanding that can be taken away from every situation. If something happened in your life, there is often a reason, imo.
Something to be learned there. Considering the harm others do to you
As created by your former deeds, do not anger.
Act such that further suffering will not be created
And your own faults will disappear.
