Maxdeath, I cannot speak for others, but I think you are laboring under a false assumption that anyone is for open borders. I respectfully do not believe this is true.
As a Michigander, I have often passed into Canada, always stopped at the border station, and spent some wonderful time in a wonderful country. I had to show ID and explain my visit. That was then. I believe one now needs a passport to enter Canada. So that border was never open. People from Windsor and Sarnia worked in Detroit and Port Huron and had monthly bridge passes. God! what a shame that this good neighbor and friend is on the government shit list.
I don't know much about our southern border, or Mexico, but to my knowledge we never had an open border there either. Nor would anyone I know want one. There really ARE bad guys out there..nobody thinks otherwise. Immigrants need screening and vetting. But can we not have both vetting AND asylum? It is said we don't have enough attorneys and vetters or whatever is required. But that's like a business that depends on customers not gearing up for peak hours and peak locations, or police departments not beefing up for a significant visit or event. There is NO excuse for not having more manpower at a border that has the most activity.
I assume you have not read most of the things coming from the Democratic Party or the left. There are a large number of those that are calling for the catch and release policies we have had for many years.
The biggest problem with the southern border as compared to the northern border is two fold.
First and foremost is that there are not millions of undereducated or unemployed wanting to cross the northern border to enter the U.S.
Second there have been almost 400 deaths each year of those attempting to cross the border illegally since they were forced on to the Arizona desert route because of the wall placed on the Mexico California border. This does not include those dying in the back of Semi trucks or in vans attempting to be smuggled into the country.
We had a law that said that children could not be held in captivity more then twenty days yet because of that law someone could cross the border illegally with a child and if caught make a claim for asylum. Because of court backup this meant twenty days in detention then release while awaiting trial. They would disappear not to be seen again. Hence the term catch and release.
The reason a visa is now needed to visit any country is because of the first bombing of the World Trade Center and 9/11.
