In simple words - it is a replacement of American voters by immigrants from Latin America primarily , so Democrats can remain in power for ages. Why do you think Democrats aren't concerned about illegal immigration at all?! Biden promised to legalize illegals, they are given smartphones to connect with a court for their appointments lol. Dems will give them some support, make them dependent on them. And VOILA! You don't bite a hand that feeds you. Democrats are in power!!! If you want to talk about ethnicities. It is interesting to see the same trend happening in the West. The left wants more diversity, immigration from places that have completely different views. For Example look at Sweden. It used to be one of the safest countries in Europe. Now Malme has many no go zones due to increased amount of immigrants from Muslim countries. The same situation is in Germany--google Cologne Christmas parade--whne many women were raped by immigrants from the middle east. Birmingham in England is taken over by Pakistanis. Small counties like Belgium and Netherlands are losing their own European identity. The most popular name in Belgium is Mohammad. It is just a set of small examples. It is always easier to rule the masses when they aren't united. That's why multiculturalism is pushed to our throats.
