"fair use laws" which are protected by our 2nd amendment.
Well, technically "fair use" may not be protected by the U.S. Constitution, and certainly not by the Second Amendment, which pertains to bearing arms. But that aside, I think what the OP meant is that forums can be asked to remove voluminous copy-and-paste jobs that violate copyright laws and be shut down if they don't comply, whether the creator of the forum is the one who posted the material or not. I don't know how often Simon has dealt with this if at all, but I think the OP is implying that if they wanted to, there are a number of long WTS literature posts that they could have had removed from this site if they really wanted to police it heavily using the weight of the DMCA.
