I don't accept their premise that gun proponents oppose health care. I think that is true of Republicans in general, but while I would concede that Republicans are better for gun rights, I do not accept that they are actually "pro gun".

Trump was certainly not pro-gun. He supported broad gun control before he was a presidential candidate. As president, he infamously called for taking guns first, due process later.

Previous Republican presidential candidate Mitt Romney promoted and signed a state-level gun ban into law; Romney was certainly not pro-gun. Most Republican lawmakers are wishy-washy at best on guns. They pay lip service to the second amendment, and then fail to support any pro-gun issues whatsoever.

The greatest measure sought by pro-gun advocates is national reciprocity - 50-state recognition of any state's concealed carry license. Republicans do not support that measure.

The Firearm Owners Protection Act adopted a uniform set of transport rules for people engaged in interstate travel. So, even if a gun was prohibited in a specific state, a traveler could possess that gun while passing through the state. Gun proponents offered an update to FOPA to allow traveling licensees to carry on the interstate if they were legal at their origin and destination. This would be a compromise to the desired 50-state reciprocity; Republicans refused to advance it.

Another big one was the Hearing Protection Act, which would have delisted silencers from the national firearm registey, and re-regulated them in the same way as pistols, rifles, and shotguns. Republicans refused to support it.

Republicans are better on guns than Democrats, but Republicans are still pretty terrible on anything gun proponents actually want.

Republican opposition to universal health care is yet another way that Republicans fail gun owners, who regularly call for such measures.
