Calling out the Spirit

Hi again! I am posting this because of a concern discussion is going around on other paranormal ghosts websites about calling out the ghosts / Spirits.
I have to agree with the messages i have been reading. That we should not be calling the spirits out when doing an investigation. I mean if there was an investigator who done this and did get what he or she was hoping for as far as evidence ,well one has to stop and ask himself was that a right thing to do ? but yet you have to stop and think about the family living in the home. When we leave they are there alone with an angry and upset spirit or ghost. I see that right down wrong!!
Yes we are out for evidence in this field but come on we have to be there for the clients as well. If you ask me if you are doing this then you don't need to be in the field in the first place. I mean you ARE putting yourself in dangers way and the people who are left behind to clean up after you!
I also have to add that i was watching the program "ghost hunters" and on that night the investigator did just what I'm talking about, Calling them out. I set there and thought OMG what a dumb ass! And frankly if anyone cares how i put this on my blogger then there are tons more websites to read :o) Happy ghost hunting...Not retard hunting
