Someone tried to kill Trump again, so we are getting more choreographed tears and sympathizing of the man from American state media. I would never advocate violence and I know I would personally be super sad at the death of a class enemy and oppressor. If you’re a socialist you should also not perform an act of adventurism that will give the regime anything that can be used as propaganda against our ideology. Even though some people may be frustrated by the situation, they can at least enjoy seeing their local news anchors being visibly annoyed that they have to go and fake cry about this again. Additionally this assassination attempt provides us the opportunity to share our political ideas with other people who may be affected by the recent event and open to new political ideas.
Communists still have an uphill battle, but things that were once unthinkable to the majority of people are relatively mainstream now, such as wishing death upon political leadership or seeing their own ideas and feelings reflected in a person labeled a terrorist by the media. The people are realizing that their social order is based on exploitation and brainwashing, they just need it articulated to them so they can begin to develop a revolutionary consciousness based on Marxism-Leninism and can articulate these ideas without the tendencies of revisionism, liberalism and right deviationism.
To address the question of why people are trying to assassinate certain politicians? Because they are class enemies, and the people do not need Marxism to understand that they are being oppressed by the ruling class. However, that does not mean they deeply understand the complex mechanisms that make their subjugation possible and perpetuate it. Even liberals and rightists are looking through their scopes to try and get a high score on the former president. The news is wailing about anti-government extremism, but in a society where the government is a tool of the bourgeois class, being anti-government is the only way of being a true hero of the people.
No contradiction there. They understand that they are being oppressed but they lack the framework to understand exactly how and why.
