It's been my experience that people who don't know what they're talking about,and this includes left wing liberals, when confronted with your facts and pinned down to state any facts they may have to refute these will do the following:
1. Change the subject
2. Begin insulting you
Example "Please cite ONE instance of an 01FFL getting into trouble with the BATF over a deal with a C&R eligible firearm and a 03FFL licensee."
I'm not the type that usually engages in crudities here but the ones that need to "STFU" are the ones that don't know what they are talking about or have an "agenda".
