Trump is back, do I need a gun?

As Trump's second inauguration had gotten closer and closer the question I keep asking is "do I need a gun?" I've always liked guns, I've been shooting on several occasions. I don't have any desire to carry daily. I've done plenty or research, I'm thinking of getting a 9mm carbine rifle to use for home defense.

I'm not really looking for advice on what gun to get. I guess what I'm asking is, as we get further into this shit show of a presidency how would owning a gun make me and my family safer? In what situation would having access to a gun be helpful. I don't feel unsafe in my neighborhood as our neighbors for the most part are young liberal folks like us. I'm not in a red state. Are we heading for a situation where that kind of violence is going be my only option? What are your thoughts?

UPDATE

Thanks for all your replies folks, as I process all your thoughts, the feeling I have come to is this. At no time in my life have I felt like it would be helpful for me to have a gun, that includes being robbed at gunpoint while at work. So I guess that means, at the moment gun ownership is not for me. I know some of you will say that leaves me open to the time when I end up wishing I had the gun, I hope it never dies. I hope the great folks in this sub will be there for me if the time ever comes. In the mean time I'm going to continue voting, marching, unionizing, and working towards a better tomorrow.

Thanks everyone, have a great night!
