The only rules that matter are those that are enforced.
When a thread is locked, the "letter of the law" has been enforced.
When a thread it locked, and the contributors/readers re-convene to have a discussion over the "letter of the law", perhaps it is time to examine the "spirit of the laws".
Appears that some feel the long-range guns should have their own independent forum somewhere else, to never contaminate the pure definitions of site and purpose as stated here. It also appears that these rules are bent now and then for other non-"pure" gun discussions.
Are the rules better bent (selectively enforced) or modified such that enforcement is predictable? Selective enforcement puts all the decision making on the enforcer. Modification of rules might make it more clear to all those charged with enforcement, as well as allow the group better understanding of how to abide by the rules.
In this particular case, when I saw a moderator taking part in the discussion, I thought it (the discussion) was in the clear, and then another mod/admin shuts the thread down two days after it was started. This is why I speak of "selective enforcement" and clear rules.
I don't know. It's not my place to say. I would like having the option to learn more about traditional/historic guns of the non-cartridge type, from the caliber of folks who inhabit this forum. But if the Masters say we shall not do such, then we sha'nt.
But also, as stated many times in this thread, I cannot think of a better place to engage in such learning. I simply don't have the resources or time or experience to set up a new forum to handle such a limited scope of guns, and would never dream of putting up anything duplicitous of this one.
