The source of TB is not “Asians” (are you from the UK ?) but is from Mexicans and similar garden spots south of there.
My wife had an illegal alien “special needs” student who showed up playing with a dirty diaper - not wearing one - plating with one. Her mother’s excuse was that she got angry if anyone tried to take it away from her ! She was (tada !) an illegal Mexican alien.
We get largely the dregs of society from Mexico and South America.
Deporting ALL their asses AND all their anchor babies would dramatically improve public health, the crime rate, road safety, school overcrowding, you name it.
I lumped Indians with Asians (as I noted) because that's the way a lot of stats are done. Originally, when I had heard that parts of Silicon Valley were 2/3rd Asian, I thought they meant primarily Chinese, Korean, Japanese and similar. Nope, there is a large presence of people from India in the tech sector that have brought extended family to Silicon Valley, and they are part of the stats published. Practically every article regarding race statistics dwells on white, Asian, black and latinos - no separate breakdown of Indians apart from Asians. I've worked with a lot of Indians in the tech sector over the last forty years, but never imagined they would grow to such a large percentage of the local populace. They are not all the same, just as with other racial groups. Some have the same mindset as us when it comes to cleanliness. But if you have ever studied Indian culture, you will find that many Indian subgroups are unclean. They don't use toilet paper, but use their hands to wipe. Along with some other nasty habits.
I don't personally know of any latinos who have similar habits. I know a lot of latinos from Central and South America, and they do not appear to be the "dregs" as is the case with Mexicans who illegally come here. Regarding illegal aliens, I agree that they should be deported. If they aren't coming here via legal paths, then they are like a disease that should be eradicated (the situation, not advocating killing people).
