Guns should be more heavily restricted in the US

I will be responding in a twofold manner, first I will address my opponent's issues with my argument's and then reaffirm my own on each topic of the debate. FIRST CONTENTION My opponent's first section related to the Idea that, "There are many causes of crime, and guns aren't one of them." But then went on to say that, "Criminals cannot commit crimes with guns without guns." And it seems to me that my opponent is debating the wrong issue in his own viewpoint. If guns are a small portion of the crime, with others mentioned like drugs being the real problem, then why would limiting guns even help? I am not saying that I believe that there are no gun crimes, I am simply stating what my opponent said. He took no definitive standpoint on the issue, but continued to flip flop between guns not being an issue and guns being an issue. Now to defend my own arguments. In debate if an argument is common knowledge it doesn't need a source,"he doesn't even back up his claims with any sources." This statement isn't relevant because this is a common knowledge issue. But because he has asked me for sources I will use some. According to this source[1] it was common to own a knife or axe in some countries(not mentioned which) but that in Germany that pretty much everyone carried some type of self defense. Also with my example in France, all nobles and some non-nobles carried swords, in addition to pistols or knives. As a defense against robbery or murder[2]. But my opponent has missed the point of it being used for self defense, which he did throughout his case. In every country with low restrictions on self defense there is lower crime, that was the point, that is the reason that the three first examples are relevant. SECOND CONTENTION My opponent next brought up the issue of equality, and how I misunderstood how he used it. First of all though, my opponent gives no examples of gun oppression, and I cannot think of any examples myself. I don't believe that guns create oppression. People create oppression with guns, and even without them they will still create just as much oppression. Now I did not misunderstand what my opponent said about equality, I simply gave an example of a similar situation. But what I did state that my opponent missed was that the people who own guns will lose their freedom once the laws are in place, just like the top students no longer have as much potential. Next he said something that is completely false. Safety and equality aren't the most important things our government should be spending it's time on, and equality is only the reason it exists in a socialist government. A government exists for many purposes, but it is not the job of the government to limit guns under the pretext of safety. Finally I would like to address the statement,"The citizens wanted slaves too." This is a red herring, which means that it is totally irrelevant to this discussion. I will address my own case. There is no reason to believe that limiting guns is a good thing especially when it comes to the civilian population, this is one of the primary reasons that I brought up the examples of the ancient and modern countries. The whole point of self defence is that everyone has it, not just some of them. And as a final note, just because you own a gun doesn't mean that you are, or have anything to do with slavery; something which my opponent brought up several times. THIRD CONTENTION To restrict guns so hard as to limit the amount of guns in illegal trade would be so harsh as to keep all citizens from owning them. Citizens of the US have the right to own guns under the 2nd amendment. There is no way to get around the fact, limiting guns is unconstitutional. Also if only the "non-normal" criminals were to have guns it wouldn't change anything, because they are the ones that commit mass murders anyway. AND if only they were to have guns, those criminals would form areas of influence not unlike the oppression my opponent is trying to avoid. [1]https://www.reddit.com... [2]https://books.google.com...
