I've recently been thinking about this topic and I will offer my insight as to why NO magician has any right to, or the reason to, discredit another magician.I'll use Uri Geller in these examples because most people are familiar with him and I like him.
1.There is no reason for Criss to discredit Uri because of this argument that I copied off of Ron White "You can watch the Uri Geller show, or you can watch the Criss angle show, they are the same price.
2. There is no moral context that should motivate you to because
A) You are a magician and you are fooling people just as much as the other guy
B) As a magician you actually run the risk of making people believe in magic (If it exists ,which I do)
C) The "psychic" is just entertaining people just like you
4. How would you like it if another obnoxious magician came up and revealed your hard earned trick.
That's just my stand and in conclusion, I'm total for fake psychics, even the scam artists.
