When the facts demonstrate that the government is, in fact, trying to take our firearms, it isn't paranoia.

In 1967, the city of New York passed a law that required all rifles and shotguns to be registered.  Subsequently, in 1991, the city also banned semi-automatic rifles and using the registry already in their possession they issued notifications to those owners that their firearms must be removed from the city, disabled, or turned over to the authorities (ie: confiscation).  In 2013, they sent another round of letters demanding more removals or confiscations.

Also in 2013, Connecticut passed legislation that required gun owners to register their firearms and magazines.  Although few actually complied, in 2014 the State started low volume confiscation of those items registered by the people who complied with the legislation.

These are just a few examples, and there are even more in other countries, Australia and the UK to name a few.
