Biden has a number of plans to discourage gun ownership. Among them, he wants to raise the cost of gun ownership by holding gun manufacturer's responsible for any deaths or wounds caused by guns. He also has a plan to force the registration of guns, which will be accompanied by a large registration fee.
Let us think about this as a matter of principle for a moment. The right to defend oneself is a natural right and also an explicit constitutional right. Freedom of speech is a natural right and also an explicit constitutional right.
Let us suppose that someone asks you if you think the person they want to marry will be a good lifetime partner for them. You, as a friend, answer yes. The marriage ends in divorce. The divorced partner claims you are partially responsible for the suffering and perhaps financial losses they incurred due to the failure of their marriage. Should they have the right to sue you for recovery of their losses? Imagine if they could do this, what this would do to your ability to exercise your right to freedom of speech. Whatever the actual impact your advice on the proposed marriage might have had, it was the responsibility of the individual receiving that advice to evaluate whether they should marry. It was the responsibility of the married person to make the marriage work or if they could not do so, to realize that the mistakes or lack of effort were their own.
The gun manufacturer has no significant voice in how the gun they make is used. It can be used rationally or irrationally. It can be used responsibly or irresponsibly. To hold the gun manufacturer responsible for the use of the gun is as nonsensical as holding the marriage advisor responsible for his advice. Actually, I would be inclined to think that bad advice on marriage would make an easier case for responsibility for harm against the advisor. At least the marriage advisor presumably has some knowledge of the two people whose marriage is being considered.
Gun registration and fees: If the government can in principle claim the power to make you register as a gun owner and pay a high fee for doing so, what is to keep the government from next forcing everyone to register for the right to exercise freedom of speech and pay a high registration fee for doing so? After all, if one right can be controlled, limited, and taxed if it is to be exercised then why would the government defer from doing the same to other rights -- freedom of speech included. Just as the Democrat Socialist Party thinks guns can be used harmfully by hoodlums, so does that host of parasites believe that Deplorables do great harm with their speech.
Do you think the party of slavery, the early KKK, Jim Crow laws, the Woodrow Wilson second wave of the KKK, segregation, the welfare dependency of many American Blacks, mandatory government school holding pens minus education, that declared Trump voters Deplorables, and the party that has always thought it moral to steal elections, would not desire such control over our freedom to exercise our individual rights that all of them will not disappear unless we throw our minds, hearts, and souls into defending every one of them?
