Should there be a such thing as "Normal"

I ask the question should there be a such thing as “normal”? And to that question I would have to say no. I would have to say no because everybody is different, even though they might dress the same, walk the same, talk the same or act the same that doesn't mean that they all the same. We all have a different style, act, walk and tone but some may just be similar. The one being the most similar seems to be the “normal” because everyone of one gender does it or because it's the one that people have been doing the longest. But what or who sets what is “normal” or not.
In Judith Butler’s video she speaks about a boy who had a feminine walk that is until he was killed by other boys who didn't like his feminine walk. Butler explains that the boy has had the feminine walk since he little and it started to exaggerate as he got older. Soon the boy was thrown off a bridge and killed by other boys for the way he walked. Butler then asks why does a boy have to be killed for the way he walks. And I can't answer the question myself but I might have a reason.
The boy was killed for his walk which seemed not normal for a male but who or what said and demonstrates a “normal” walk for males. Gender sets these “normal” roles that one should do based on his gender. The reason I believe that the boy was killed for his walk was because the other boys were afraid of the walk becoming normal for males. Males are taught how to walk like a “male” just by observing and that sets the “norms”. People based what is normal by the majority. If males started to walk in a feminine way then sooner or later the walk will become normal and that's what the boys feared of the walk becoming so they killed the boy. Genders are supposed to be walk a specific way, talk a specific way, act a specific way and dress like a specific way because if they don't then they will not be seen as normal but different and that's what people are in fear of being seen as. A male doesn't want to be seen as “gay” or “homosexual” as the same goes for females.
  In the end a person shouldn't be killed for doing something that isn't considered normal to them as one thing may be normal to one country or person but unusual to others. People need to realize that everything changes including the “normal” way of doing things and therefore there shouldn't be a such thing as something to be considered “normal”.
