You see it as attacking? I see it as venting.
Survivors of abuse forums probably vent and criticize their abusers highly too. I find it hard to stomach the notion that it's attacking.
Great for you that you don't find a need to vent and criticize the "religion" as you call it. Sounds like you are not nearly as scarred as some of us.
Instead of criticizing (which by your own definition is also attacking) those of us who were physically/spiritually/verbally abused, perhaps you should educate yourself first. You know, try to understand others' perspectives. :)
For example:
Besides the "selfish" reasons, speaking out has literally saved countless people from the grip of a harmful course of action.
