When we have elections in the UK; I feel fairly confident that they are conducted legally. I would not like to live in a time when the citizens bring down a government with guns.
If you allow your citizens to own as many guns as they want, they are free to use them in any way they want. Have guns ever been used to bring down a government in the US.
So your feelings are the gauge you use to decide things. Emotions are a poor gauge to use when deciding what is best. Our emotions are highly susceptible to manipulation by outside forces.
Who wants to live through a revolution? Not me. But if a revolution is required to maintain liberty I would rather live through a revolution than live without liberty. Would you rather live in North Korea than live through a revolution? In other words, live permanently without any liberty of conscience, freedom of religion, freedom of speech, etc... rather than live through a temporary revolution to maintain your liberties? Remember, once liberty is gone the only way to regain it is through bloodshed. You cannot vote your way out of totalitarianism.
Up to this time this time there has never been an armed revolt in the US, but our liberties have never been under such attacks as they are now either. But, the founding fathers recognized that what is happening today in our country could very well come about. That's why they guaranteed the right to bear arms.
Liberty is something worth taking risks for, for only with liberty is life worth living. Being told everything you can do, everything you can believe, everything you can speak about, under threat of death or imprisonment is not a pleasant way to live. Look at what happened at Tiananmen Square and why it happened. The people were peacefully demonstrating for liberty and the Chinese government ran them over with tanks. They killed 10,000 plus of their own people to maintain the government's dominance over every aspect of their citizens lives. You would rather live in that type of system than own a gun? Really? You care nothing for your own liberty? Stalin killed millions of his own citizens in some very horrific ways to die, and doomed millions more of them to lives in the gulags where they were starved and worked to death. You think living like that is better than owning a gun and fighting for a life worth living?
