To my read, and again without having read the thread, yes.
Asking for a cite is not JAQing.
In this case I have no idea if the gunpowder used in fireworks comes from the same manufacturing supplies as the gunpowder in bullets or not. I do not know what the NRA actually blocked. A law that proposed taggants in all gunpowder or a law that proposed taggants in gunpowder that went into bullets only? I am not so sure why I should care about the distinction and do not. Looking briefly I do find this claim:
Is that true? I don’t really care and I have no desire to hijack this thread into that one. But debating which is true and asking for a more definitive cite for a claim to the contrary seems very within bounds and is NOT claiming the contrary. If you had provided solid proof that the NRA had never done anything that would have blocked taggants in the gunpowder that goes into fireworks and he ignored your proof and subsequently claimed they had, then he would have been guilty of what you have claimed he did. You provide no evidence that such happened. Maybe it did, but nothing you have brought here shows that.
Just my read.
