Sure but like it or not Mexico isn't part of Central America. The populations of central American countries is tiny - I think Guatemala is the largest with 16-17 million people. Mexico is around 140 million with 10% of its population at the very least already living in the USA. Don't get me wrong I don't want any of them here illegally but these are just basic geographical and population type facts that are very easy to check. Making wild exaggeration on those type of things erodes credibility on the large points.
Further the 179 million figure someone pulled out of their ass would only be true if the entire populations of all those countries up and came here - all of them.
That's just absurd
