I've never been asked about why so many since I tend to not disclose numbers, but it is known by some that I own guns and some do eventually ask why (if they are unarmed of course).
I put on my somber, logical face and reply that it is for defending myself and my children, hunting if needs be (I do not hunt, but will when there no such thing as a grocery store) and for pleasure.
This answer tends to drop their guard.
Then I put on my crazy faced wicked smile and say that they are for fighting a tyrannical government, killing those that need it, and the voices in my head said I should have them.
After which I have a good laugh at the horror in their eyes and say something the effect of "I am no more of a danger to you than you are to me".
Sometimes it works out positively with those who have some intestinal fortitude, the rest just ignore me from that point forward.
I am not in the PR buisness and I let it be known from day one.
Gun ownership is an inailenable right and it is about time all the wimps had to face facts.
Live with the gun owners or get out.
