"The Trump administration’s deportation of DREAMers, building of walls, refusal of refugees and revocation of visas moves everyday Americans further and further away from ever observing the possible advantages of diversity and pluralism."

That doesn't even qualify as gibberish. It's quite easy for Americans to bump elbows with diversity and pluralism without the need for illegal immigrants or people who can't be vetted under the current system. Canada should welcome more MS-13 members and let it be America's loss.

This is written as if you think your readers are dimwitted. 'Diversity' is about as specific as you get when it comes to realizing the benefits that come with  changing the fabric of your society. In many countries Canada's immigration program would be considered racist and untenable and here you are lecturing  them as if you make diversity work to the extent that you do because of good genes.
