Sergei believes that every rational and sane person should have a gun. No Sergei is not like loud mouth Texan who shoots his gun in air at times of joy. Sergei is just thinking that if nobody was able to get a gun then those who had them would rule society. If everybody did have a gun then it would make people think twice about doing any thing violent towards anybody. Look at Switzerland, they have one of the lowest crime rates in the world, but they have one of the highest gun ownership rates.
