From a legal immigrant who was there, here:
What I did see, however, was fear. Fear from the rally attendees for their immediate safety, and fear of Donald Trump from the protesters.
More than that, I feel that I experienced today, for the first time in my life, true totalitarianism and authoritarianism, expressed laterally from citizen to citizen, in order to silence opinions from being shared. This enforcement was shared through sheer numbers and intimidation, and in a few cases, violence.
People brought their children, loved ones, and friends to attend the Trump rally. I saw an older Asian man and his white wife in attendance, and the looks on their faces when the rally was declared cancelled almost broke my heart. I saw scared children clinging to their parents’ sides as they exited the building to the screams of protesters. I saw a quiet, but excited crowd of Donald Trump supporters get thrown out of Chicago.
Worst of all, I saw the first amendment trampled, spit on, and discarded like trash.
