A good question, and a fair one. I can see where this would be a mystery to some people.

I can only speak for myself, of course, but the answer in my case is very simple.
I love the paranormal.
That's all there is to it. I grew up in a house of believers, and was a believer myself. I read and watched every thing I could about the subject. Even after I came to my current understanding of things, I never lost my enthusiasm or delight at the possibilities that paranormal subjects offer.
Far from ruining it for me, my skepticism offers me a new way to enjoy my favorite topic.
You see, for me skepticism and critical thinking is about much more than the paranprmal. I utilize my critical thinking skills in almost every aspect of my life. They inform my choices and have always served me well. I use them in my work, when making a major purchase, and when pursuing my other hobbies, the study of history. I enjoy geting to use and improve my skills, and the paranormal is another way to do it.
I also hope to meet some interesting people and have some good conversations.

While I am on the subject, I would like to list a couple things I
do not come to paranormal forums for:
I don't come to fight.
I don't come to ridicule.
I don't come to judge others.
I don't come to make people see things my way.
I don't come to build myself up by tearing someone else down.
Sincerely, Canis
