I use brainwave generators and selective music which effects DNA all the time for my own reasons, but it is my choice and even tho I am a practitioner I would still turn it off while reading forums were I not in the mood
I suggest simply informing people of this great technology and let them make their own minds up
as far as negativity, I am so used to CNN, BBC, NBC and Washington DC that any ole negative thing you toss my way just rolls right off the shoulder.
I dont mind the dialectic so much as long as it is constructive and a learning experience for myself or others and is done in moderation and from a place of love
as far as the plug in for Firefox, I just use
real player because you can right click any streaming video anywhere and download it to your computer
peace
