To each his own.
Some people do "activist" type stuff to heal themselves, not necessarily to reach others. I cannot take issue with that. This is a dangerous, deadly, harmful cult--so what if they get a little heat (as long as it's ethical/legal)?
Other people do ineffective, potentially harmful things because they don't understand how to do something much more effective. If they put themselves out there on the forum stating they're going to do those things, I figure they must be open to discussion about it.
Others have worse motives, such as for personal gain. If that's the case, they deserve ridicule.
In the absence of poor motives, illegal/unethical activity, and acts that will make things worse, I say live and let live.
