Even the notion of private property giving the owner the right to forbid firearms is unConstitutional. The wording is RKBA shall not be infringed. There are no qualifications, no exception. No government entity nor any other entity may infringe. It is absolute. I tend to allow the owner to say whether he wants guns on his property or not but that also determines where I will do my business.

Wrong, the Constitution forbids the United States and the several States from infringing the rights of the People.

One of those rights is for individuals to determine what happens on their property.

You are not violating free speech if you told someone with a Rainbow Flag t-shirt to cover it or leave. They could do the same with your weapon on their property.
