No, and we should implement an open border policy

We shouldn't let people flow into the US, there has to be some sort of restrictions for safety and health.

An open border policy allows anyone, and that means truly any person, to cross our border and enter the United States. In the event that this occurs, there is no measure to ensure they aren't some kind of spy, suicide bomber, terrorist, or other threat to society. If you are going to allow people from one place to another, there needs to be some form of regulation to ensure whomever is entering is not a threat to society nor the economy.

If we implement a full open border policy, I believe that it would be encouraging to people who could be seen as threats to our country to enter the country illegally and cause harm to the citizens living in the US

How do you plan on preventing child sex trafficking, the trafficking of dangerous drugs like fentanyl, the death of people during illegal border crossings, and letting dangerous men into our country if you are not controlling the border and vetting who enters? We are not a sovereign nation if we have no borders. I think you don't actually care about these people, and instead want this policy because you think these people will give you political leverage and future Democrat voters.
