Well, no, and yes.
I and probably most people own and wear hoodies, however in Britain we have many gangs of scum who love to stand around the most boring places (bus stops, outside shops), drinking and starting fights with random strangers passing by, and they nearly always are wearing their hoods up. They all walk the same, talk the same, act the same, and wear the same clothes.
For example, you, especially being American, if you were to walk down a street near a gang of these hoodies, for NO REASON ATALL, they would come over to you, get in your face, berate you, and then beat the $hit out you, probably sucker punch you first, if you tried putting up the good fight which is pointless because you'll nearly always be hopelessly outnumbered, you will probably end up getting stabbed, they will spit on you and while they are beating you to the ground, you can almost guarantee one will be filming it With his mobile laughing, then one will probably urinate on you. They are scum, and we have them in untold numbers across Britain, Americans don't know what Britain is like, they think of violence and fights in Britain and laugh at the thought, but from what i remember, we are one, if not thee worst in Europe for violent crime and binge drinking. Many Americans see what they are shown on American TV shows and think that is what its like, but until you come over here, you have no idea. haha
That being said, we are mostly great people, and i wouldn't want to be anywhere els. :)
