Actually, none of that is true. Radiometric dating is highly reliable, and has been confirmed by a number of seperate methods.
Much like a pan balance corrobrating a kitchen scale, the methods corroborate each other because, due to their different mechanisms, it's impossible for a given circumstance to affect them in the same way.
You're completely misinformed about radiometric dating, JF. I suggest you ask some questions and learn from the
real geologists who post here. I know I've learned a lot from them.
