You are the epitome of ignorance that the majority of this fandom represents.
First off, let me start off by saying, I would NEVER touch him without his permission. I would never poke his ass randomly like that. EVER.
Now let’s move on. What you described as sexual harassment (i.e. Rape touching in places they shouldn’t) is actually sexual assault (by the way, poking is a form of touching). So essentially you’re saying she sexually assaulted him.
Now you tell me, if a random guy came up to you and poked your ass, what would your response be? Because I would feel violated and very very uncomfortable. If you watch the video, yes he smiled, he also jumped and looked very uncomfortable.
What that girl did is sexual harassment, and borderline sexual assault. It’s not okay because Harry is famous. The fact that he’s famous doesn’t transform him into an object that we as fans can do what ever we like to. He is a person. A human being, and NO ONE has any right to touch him like that. He’s there to perform. Fans are there to watch. Keyword: Watch. Don’t touch. ESPECIALLY ON HIS ASS OR OTHER PRIVATE AREAS.
The fact that you don’t see anything wrong with it is terrifying. Because you are clearly the type of person that would jump at the chance to do the same or worse, so personally, for his sake, I hope you never ever get the chance to meet him. Or any of the other boys for that matter.
