I Think that This is Intentional

I just noticed that there is a lot of physical similarity between anti-alien bigot Ben Lockwood/Agent Liberty (played by actor Sam Witwer, right) on Supergirl, and Alt-Right bigot Ben Shapiro (played by useless sphincter Ben Shapiro, left).

The story arc of Supergirl, prominently features an anti-alien movement in the United States.

This arc is unequivocally an allegory for the anti-immigrant movement in general, and the Alt Right in particular, in the United States.

I am thinking that this was an deliberate decision by the producers, and I wholeheartedly approve.
