1.) Again your assumption that if the Government wanted it could have easily rounded up everyone in the populations AIDs was first clinically observed in as well as anyone they may have had contact with and lock them up for life if they tested positive is beyond ridiculous. No one would submit to testing if that was the case!
Just in the populations that AIDs was first clinically observed in:
There where thousands of people infected with HIV from blood products in the USA alone, thousands more in Canada and thousands more in Europe (about 6000 in the USA alone) a whole lot more then that would have had to be forced to submit to testing knowing that if they tested positive they would be locked up for life (at least 15 thousand as well as their spouses, children or anyone they may have had contact with.)
There were thousands in the G– Community that was mostly underground and very few would admit to being part of (another contributor due to “Conservative” moral ideas)
There were thousands of people who since the early 70s had used an intravenous drug and anyone they had contact with.
Thousands of Americans that had either been to or had contact with a Haitian.
Just in the population that AIDs was first observed the government probably would have had to “quarantine” over 10,000 people (lock them up for life) and since those people would have been having relationships with people outside their circles for up to 10 years while carrying HIV it would not have helped anyway.
Education is the only thing that has helped at all and gotten people to submit to testing and reduce their own chances of contracting the disease
2.) Regarding ebola: we are discussing if a travel ban would be affective. Quarantine and/or testing of those entering from those countries would be fine, you are trying to change your position or simply forgot what we were discussing or are “moving the goal posts”
