I'm just putting your question in context.
Regulating the conditions under which the firearms industry can be sued is one aspect of firearm regulation. You talked about not wanting the government to infringe on our fundamental rights; well, one fundamental right is the right to seek redress through the courts when someone has wronged us.
If you're going to talk about restrictions of rights, remember that laws like the
Protection of Lawful Commerce in Arms Act (to use an American example) is also a restriction on the rights of the people.
Allow a freer expression of the rights of the people and you may find that firearm owners are even more restricted by what they can do... not by government regulation, but by the invisible hand of the market.
