It was an interesting book. Many of the ideas resonated with me - governments only tend to become bigger and our rights only tend to shrunk further. There are laws against whom one party can make noises but they will never repeal them or improve them. One cannot get more freedom by simply asking for it. Voting, as many of us suspect, is not the "Be All, End All" of being a good citizen.
But, the book has been written is a US specific context. While the basic principles hold, many of the lessons don't apply right now and the situations discussed may feel align. So while it is true that in general governments tend to acquire more power over time and reduce citizen's freedom, in India, we have significant movement in other direction as well. We recently got the Right to Information which is immensely powerful and if someone would have ask me, I would have never believed that Indian politicians will actually pass something like that. Although since then, there has been constant tussle at limiting it's scope and putting things outside it's purview. So we are back in Claire's territory. Similarly, we are expanding women's rights. We are expanding tribal rights. So we may be on a slightly different trajectory. But we do need to be constantly vigilant.
Also, while I admire her passion about gun rights, I find myself on the other side. My position is not a well considered one and might be more of a psychological thing, plus the different environment I grew up in, but I am sticking with it for now. But I do agree that it makes sense to legalize things like prostitution and drugs. And if I understand correctly, the arguments in these cases is that once legalized, they can be better managed - not really an argument for less government intervention. But I wouldn't trust "free market" with these things either.
So while it is an interesting read, if you are not from US, there may be better books to get introduced to these ideas.
