Build The Wall And Secure The Border, Yes or No?

I have questions—about its effectiveness considering that people are here illegally from all over the world, many who simply remained after their work and student visas expired. A wall won’t stop that. Then there’s the issue of the [b]lies[/b] about its funding. Trump insisted, “Mexico’s paying for it.” So why was the national emergency necessary to strong-arm getting the money from taxpayers (ultimately) ? And Trump has a problem with [b]legal[/b] immigrants from places [b]he’s[/b] designated “sh*thole countries”, preferring European immigrants (which he’s stated on more than one occasion). So, sorry, but I believe Trump’s concerns are less about the legality (he’s had undocumented workers at his own properties) than whom he perceives is coming, and he plays to his supporters’ racism.
