A Trump rally is like a mixture of a rock concert and carnival atmosphere. People go there to have a good time. This is why people will camp out to get in.
To me it is not about the words of the chant, but rather it is about the emotion behind the words. The crowd at the rally was having fun, and the chant became a spontaneous part of the fun.
If you ever went to a professional baseball game, members of crowd will yell taunts and insults to the opposing team players. You will hear things like, throw the bum out, or go back home you loser. This is part of the fun and is not taken to heart, by the players. Their home crowd does the same thing. Leftists have too much hate in their hearts, to where they no longer have a sense of humor.
At Democrat rallies or counter rallies, there is a lot of hate and anger. The leftist are projecting their own hate and anger, and assume these words were based on that angry foundation. They cannot understand friendly taunting. If you watch the crowd, they were smiling like someone at a ball game, to a creative taunter, who comes up with clever stuff, that even the opposing players laugh at.
The left is so full of internal stress and battle fatigue, that they no longer know how to have fun. I suggest watching the crowd at the rally and you will not see anger, but rather fun, excitement and audience participation.
PC has purposely confused words and emotions. It defines hate speech by words even when there is no hate. It also ignores hate if the words are not on their list. All insults against Trump have a hate foundation but that is not called hate speech, even if it is fueled by hate. Fake News is also Hate News. A rational mind judges by the emotion, since this tells you the unconscious intention. Buzz words first is backwards, irrational and emotionally deceptive.
