Stopping flights from west Africa wont stop west Africans from going to other parts of Africa and flying out.
True, but it will reduce the number of people from outbreak countries, and by making them take longer to get here (and don't forget, other African countries have stopped allowing flights from outbreak countries), they're also more likely to get caught by airport screening.
In fact if you say, "we are going to shut down travel from west Africa" thousands of west Africans are going to try and flee the area.
Thousands are already trying to flee.
Unless the entire world stopped flights out of all of Africa the sick will simply fly from another part to Europe, or Asia, or central America or any where else. Shutting down all of Africa is impossible.
Nobody is suggesting shutting down all of Africa. And the idea that if a measure isn't perfect then it's not worthwhile, which is essentially what your argument boils down to, is simply nonsense. There's a reason that other African countries have already taken this simple, sensible measure.
Now it would be much much easier to close the border with Texas and stop all flights in and out of texas, blockade the ports and turn it into an containment area.
Yeah, no. It's easy to shut down Texas
airports. Closing the
border of Texas would be a harder job than closing down the US-Mexico border (it would be fun to see Obama try, though). Seriously, the border of Texas with the rest of the US is about the same length as the border of the US with Mexico, but there are no existing checkpoints, there's a lot more roads, and the terrain is more hospitable. And again, we
don't need to make it
impossible to get from outbreak countries to the US in order for it to be worthwhile.
I'm sure that, given how completely stupid the idea of quarantining Texas is, you thought you'd illustrate how stupid you think banning air travel from outbreak countries would be, but your point fails because your claim is simply wrong.
