I don't get it.... why do people refuse to accept that their opinion is not necessarily the opinion of everyone else??
Opinions are based on personal experience. Personal experience is different for different people. This means the perception of the truth is different for different people. Some can see the truth, others no.
The truth is universal. It is based on the reality and there is only one reality. Wheter your opinion corresponds to the reality is a matter of knowledge or awareness. You are probably not aware that the goupr you are refering too uses cult-like pratices that are damaging to many people, but others are. It is the reality. If it's not damaging to you, good for you. You are kucky. But if you care for other people, you should consider all those you have seen there lifes disrupted or destroyed by such cults.
This is the reality. You cannot escape it.
An example of an opinion:
"Is the earth flat or round?". Is this a matter of opinion ?
An opinion is an "insight" that must be confirmed by scientific fact to be declared valid or invalid. I don't agree that your opinion is just as good as mine. The reality holds the truth. In case of doubts about the risks involved for a given "mind" technology, it is preferable to stay on the safe side and to avoid.
