Health,
1.) Regarding HIV:
The piece that you copy and pasted above does not contradict what I wrote in my earlier comment. It’s a paper on the situation in a location called the Veneto region of Italy in 1986. Nothing to do with the USA or the situation in general (although even if it did it wouldn’t have contradicted what I wrote.) You clearly don’t know much about this subject at all. Again you should try learning a bit about it, it’s a fascinating topic. (A slightly irrelevant fact is that Ronald Reagan was president in the early 80s he wasn’t exactly known for running a “liberal” administration and it was administration that responded to the first discovery of AIDS)
2.) Regarding Ebola:
Again, a travel ban would not prevent the disease from coming here so it wouldn’t save lives. All a ban would is wreck the economy and give the virus more of a chance to mutate which would result in a deadlier strain coming here which would kill more people.
