Let me preface this by again saying the only gun I own was one handed down to me from a dead uncle. Had that not been given to me, I would own zero. That gun is put away and there is no ammunition for it in my house. In fact, there has never been ammunition for it in my house.
With that out of the way, yeah, if I was going to go out and purchase one it would probably only be in response to things I saw from the U.S. government and the followers of whoever happened to own the levers of power at that time. I will be frank, I find the people running the narrative on the left to be cuckoo. Now that is not your every day rank and file Democrat, but some of the most vociferous people on that side of the aisle are nuts. And, as they are the most active, their nuttiness is infecting the Democrats. I do not trust the far left. Conversely, I had a Facebook discussion with a guy the other day who is supposed to be on my "side" who scolded me for wanting to give up my rights because I was willing to accept some curtails on the 2A. This guy argued that the 2A allowed for equal armaments to the government. I tried to pin him down as to whether that meant I could own a nuclear ICBM and he refused to directly answer that but merely followed up with, "It is people like you who have thrown away our rights..."
So the point of all that. I find the fringe of the right and left to be certifiable. They pull more political power than I do because they have the time and the desire to be more active. If either of them were to obtain the ability to truly impose their will on us, I want a way to go out with a fight. I would lay the odds of that happening somewhere at .000000000001%. Thus why I do not own a semiautomatic rifle. I do not want to **** over some future generation because, "that could never happen here" though. So I am willing to go along on some control but I do not want an outright ban.
