So he should be blamed for what his followers say and do then? Assuming what he means, without him saying it is not how to go into anything. That's why everyone knows fake news is a real problem.
Should Justin Timberlake be blamed if one of his young girl followers kills herself? See if you look at things in this way, it results in a dangerous conclusion. Trump should worry about what he says and how to run a country. Trump can't control what someone else does, that is not his job, nor should we expect that from him. We should treat Trump like we did every other president for him. Is he perfect? No. He is very charismatic and knows what he needs to get done, which results in his followers being a little overly optimistic at certain points. That's why I voted for him, he isn't a hack politician he is a businessman.
This works on both sides, Antifa attack Trump supporters for wearing a red hat on there head. Does this reflect a problem in the Democratic party as a whole, yes. BUT this is not every single Liberal out there. I do not support most Liberal ideals but know they are not all crazy lunatics.
