As has already been said, comparing property rights and the God given right of self protection is not a valid arguement nor does it make sense.

If you posted a no tresspassing sign on your PRIVATE property, I would not tresspass. If I did I would expect to be approached. But either way, you would never know I was armed.

If you owned your own business and posted such a sign, I might enter if I chose to do so. And again, you would never know I was armed.

If I had to defend myself on your property, the last thing I'm concerned about are your property rights.

The right of self protection and preservation trumps any and all such property laws.

I defy and oppose anyone who tries to prohibit me from protecting myself because they don't like guns. Of course I will abide by Federal and state laws but that's it.

One major factor that some of you are forgetting is CONCEALMENT. If I was open carrying then maybe you would have a valid arguement.
