You shouda seen the crap I believed when I was the age at which Lennon wrote these lyrics. I was also convinced that Linda Ronstadt was waiting just for me ... :))
Its a fact that children’s milk deaths occur far more frequently in homes with milk in the frig. Hence, the inescapable conclusion that milk must be banned from home where children are present. Not extreme -— if we save just one child it will be worth it ...
Your assumption that an employer must justify regulation of employee behavior and speech in the workplace is simply too juvenile to warrant an argument. So, your position fails.
Nice try, but fail! No, you can’t justify bringing a gun onto the employer’s private property in order to prevent being raped. Your employer has an obligation to provide a safe work environment -— and one that is free from sexual harassment.
As for the “arguments” questioning the harm a gun could possibly do, that is for the private property owner to decide, not you!
If you are in an area of the employer which is not open to the public, you have no “right” to do or possess (or say, or that matter) anything which the employer prohibits. If you are in a “public” area owned by the employer (i.e., not on anyone’s private, controlled property), then you do have rights which can be adjudicated.
Many of the problems in this area of “rights” stem from employee use of parking lots which are also used by the public. There are some employers who have tried to prohibit employees having guns in their cars while not exercising the same restriction against non-employees, which is certainly unfair and perhaps even unlawful in some jurisdictions.
