The treatment that reporter got when she got close to Trump is no more severe than the treatment anyone gets from a bodyguard if they try to approach someone they should not approach.
I once saw a woman jump up on the stage and try to rush Elton John at a concert. She did not reach him--his bodyguards leaped on the stage and grabbed her firmly by both arms and pulled her off that stage. The whole event lasted less than a minute. Elton John, being a skilled and professional showman, only backed away a few steps when he saw her coming towards him and did not miss a note.
That reporter was not roughed up--the bodyguard firmly removed her from a position she should not have been in. If she has a case for charges against the bodyguard (aka campaign manager), then so does everyone who has ever tried to get near a public figure and been stopped by bodyguards. Usually, in those cases, the person rushing the public figure gets blamed. But since this is Trump, some are trying to blame him instead. It's the same mentality that blames him for the violent leftists trying to disrupt his rallies.
Your story and narrative in your example does not match the actual event that took place.
You are Trumpsplaining when you should be ashamed to back an embarrassment and his whole campaign.
