I don't think a person keeping 1 **** bass is going to hurt the bass population in the lake. I am sure the fish and wildlife would not leave the size limit 12" if bass were low. It is also his legal right to do so. He could have kept them all and I do see an issue with that but he did not. I am sorry that they guy called you an idiot but all fisherman around here are not like that. He probably is one of those fisherman that thinks if you don't fish for bass that you should not be on the lake. it is sad the way some people are these days.
