You said "every gun owner, ..." I don't believe every gun owner necessarily has an oath to office, but I'll take you for your word that it wasn't a call to violence. However, the only way the second amendment could be repealed is via a constitutional amendment, which by definition is constitutional, so everyone who is sworn to uphold the Constitution would have to abide by that amendment (though I doubt it will ever happen, as has been mentioned, amendments are very difficult to pass).No not a call for violence a call to fulfill their oath of office. To protect and defend the constitution. Taking away anything from the bill of rights is an overt attack against the constitution. Far worse than for instance 1/6. It's more in the nature of a prediction.
