Well, I don't ignore them, and IMO, you made some very good points.
There has to be a reason why changing the rules of the range is more important than dealing with the "scofflaws" that are not following the rules of the range. Punishing the good members by changing the rules of the range is letting the bad apples spoil the whole barrel for everyone. If anything, get rid of the "scofflaws" & you all will be better for it.
So, simply tell them that they are doing the same thing as the Gun Control folks are doing & making more laws when they simply need to be Enforcing the Current Rules.
Adding more rules when they do not enforce the Current rules is really stupid.
It is like building a taller fence when the dog that has been getting out of the fenced in area it is kept in, even though it is escaping because folks keep leaving the gates to the fenced in area open instead of closed.
So changing or making more rules is not the answer to the issue of rule breaking.
Really Enforce the Current Rules. No matter Who breaks them...
Simple solution to the problem.
I can almost assure you that if some of the "rule breakers" are punished for their actions word will get around that it is not a good idea to break the rules.
If nothing else, the first or first few rule breakers will complain about the rules getting enforced for the first time in a while & that will get the word out if nothing else does. "Sacrificial lambs", for their rule breaking actions... They deserve it anyway...
G'Luck on convincing the "board" about this simple, "Enforce The Current Rules", concept. If they seem to balk about it, then there will likely be some other reason to make more rules than what appears to be the case.
