Just the same as i will not let the very slim chance of someone braking into my house to do me harm will decide for me how i chose to lead my life. I would only carry a firearm because i felt needed to not because i could.
I've read that the civilian gun laws in Ireland are quite strict, and that a majority of the population supports those strict laws. I couldn't live in a country like that. I sincerely believe that we all have a God-Given right to self-defense. I read several accounts of the recent London riots (where there is similar strict gun control) I was amazed at the accounts of law abiding citizens, cowering in fear in their homes, with no more than a hammer or steak knife to defend themselves.
