You seem to think that the only possible result of a repeal of the 2nd Amendment would be an outright ban on all gun ownership by private persons. But there are a lot of possibilities that fall short of that drastic step. We regulate the use of many objects in this country and the result of that regulation hasn't resulted in an outright ban on most of them. Automobiles are a great example of that. Using the argument that repeal would inevitably lead to confiscation of everyone's guns isn't a good logical argument. It's simply a scare tactic to frighten gun owners. With millions of gun owners in this country who also vote, repeal of the second amendment would not likely lead to a complete ban. There wouldn't be the votes in Congress for that. There would likely be more regulation of guns, and people have legitimately differing views on just what kind and how much regulation is needed to help address the large number of deaths to firearms that we have in this country. A number of other democratic countries have far more restrictions on gun ownership without an outright ban and they have very low deaths from gun shots and don't have the tyranny that you are concerned about. A repeal would only guarantee one thing: that the government could regulate guns to the same degree that other objects are regulated. What regulation would finally result from that is impossible to say with any high degree of confidence, except that I think a complete ban is not the most likely of outcomes.
