Add to the above a little fact that these Democrats don't want us to think about and that is illegal immigrants have way more of a negative impact on African Americans than whites. Many white people and businesses in general, such as the agricultural trade in California, benefit greatly from illegal laborers. It is well recorded that illegal immigrants take away jobs from African Americans. Many African Americans are killed by illegal immigrants especially due to the drug trade and gang activity.
It's very easy to prove that it's not whites who benefit more from having a border wall, it's people of color. But this doesn't stop Democrats from demonizing white people over this issue. To purposefully divide our country over race, when they know the truth, is horrendous. I just hope that someday more Democrats will understand what their party leaders are doing.
