Excerpt from BBC "What is populism, and what does the term actually mean?"
https://www.bbc.com/news/world-43301423
"In political science, populism is the idea that society is separated into two groups at odds with one another - "the pure people" and "the corrupt elite", according to Cas Mudde, author of Populism: A Very Short Introduction."

Further, the Encyclopaedia Brittanica gives an excellent explanatory and definition including this excerpt.
"In its contemporary understanding, however, populism is most often associated with an authoritarian form of politics. Populist politics, following this definition, revolve around charismatic leaders who appeal to and claim to embody the will of the people in order to consolidate their own power. In this personalized form of politics, political parties lose their importance, and elections serve to confirm the leader’s authority rather than reflect the different allegiances of the people. Some forms of authoritarian populism have been characterized by extreme nationalism, racism, conspiracy mongering, and scapegoating of marginalized groups, each of which served to consolidate the leader’s power, to distract public attention from the leader’s failures, or to conceal from the people the nature of the leader’s rule or the real causes of economic or social problems."

The recent tragic event in the US demonstrates the consequence of inflaming the minds of those who object to your message.

Perhaps the message was strongly supportive of the POTUS figure presently habiting the White House, and maybe there was a clear encouragement to convert as many individuals as possible to further support the mindless narrative of the Leadership.

Either way, I am sorry that you are no longer with us Charlie, but it is a deep shame that should be felt by all that your passing was a politically motivated event. Just what motivated your attacker is yet to be determined, but the options probably include a split in the Republican Party or an element within the Democratic Party.
How this might unravel, time will tell. It must serve as a warning to others not to be seen as the promoter of ideals that other people will object to.

IMHO
