Request: Please stop using the 'brown people scary" tactic - as a "little brown man", it is highly offensive and rude. You want to make a stand on racism, use your own race and leave mine out of your conversations. IMHO it is just as racist. Please stop.
I didn't make the claim, but it has been discussed in any number of places over the last four years.

Mexico meets migrants at southern border with armed forces
Mexico meets migrants at southern border with armed forces
MEXICO CITY (Reuters) - Mexican soldiers, armed police and migration officials blocked hundreds of migrants after they crossed the border from Guatemala in a caravan into southern Mexico on Wednesday, and detained dozens of them, a witness from a migrant aid group and an official said.
The operation in Chiapas coincided with a meeting of Mexican and U.S. officials at the White House on Wednesday to thrash out a deal that would avoid blanket tariffs on Mexico threatened by U.S. President Donald Trump last week.
Trump announced the tariffs in retaliation for what he called Mexico’s failure to stop Central American migrants from reaching the U.S. border.
Well looky there - less than 22 seconds and there is an article from Rueters showing how President Trump stopped the practice in cooperation with Mexico.
But wait! There is more!
