So if some sicko makes a demented video about the upcoming Democratic Nominee you would encourage everyone to watch it and rail against the nominee because of a video that he/she/they was not involved in?
If you read my original comment, it expressed regret at the low esteem in which our independent press is now held, since I believe a press that is free to adopt an adversarial position toward our political leadership is what has always made our free press the "watchdog" of democracy. And, in that video that you are referring to, the figure representing Trump is acting violent toward several members of the media, among other segments of society. My focus was on him shown doing violence to members of our free press, be in print, or broadcast journalism.
I don't believe Trump created the video, which I believe is what you were asking me. If, however, I consider that the president, on many, many occasions has referred to the free press I am myself referring to above, as "the enemy of the people", then, yes, certainly he has contributed, among his followers, his supporters, and his cult, to the anger and hatred of the press that most certainly comes through in that video. Just as he bears some responsibility for the words he has used to demonize many immigrants.
The president's words count. I take him seriously. When he tells American citizens who are not white to "go back to the country they came from", and when he labels our free press "the enemy of the people", then, yes, he bears some responsibility for the attitude his followers embrace on those two subjects.
He did not produce the video in question. Would it have been produced absent the attitudes expressed by Trump over the past 3 years? No, likely not. I don't see how it would have been produced without the maker taking his/her cue from the attitude and words of the president himself. Even were Trump to condemn the video( and did he, I forget?), he would still be responsible for his contribution to the demonization of the watchdog of our democracy, a free press, a press free to disagree and criticize the president without being labeled "the enemy of the people".
Anyway, that's where I was coming from, regardless of your opinion of me.
