Read this article about disruptive people here.
I think that intent is always a great way to figure out who you should believe in, or how to handle people that you think are disruptive. I do count people who have been called “disruptive” as some of my closest friends. I am privileged enough to be friends with crazy people, or people who just suddenly do something to shake up the status quo, and sometimes it seems that these persons have no rhyme or reason in doing so, but if you ask them about it, and you ask them with an open mind (and heart). Tada! It will make sense and they can bring you along for the crazy and fulfilling ride that might eventually change your life. 🙂
That said, some people may just enjoy being disruptive, to rile people up. Again, intent is everything. 🙂
