Сибиряк, если не возражаешь (that may not be 100% accurate though):

"I can be not right, I can make mistakes but it is my opinion and my mistakes. If I said so, it is mean I think so and i will be not saying if I do not think so. Better I will be saying my mistakes, than to repeat the mistakes others."

=> I may be mistaken, but that would still be my own opinion and my own mistakes. If I say something, that means I think that way, otherwise I would not have said what I said. I prefer to rather making my own mistakes than repeating mistakes of the others.
