wptw is absolutly correct.
They may feel that you are cutting into the pie of new members on campus and do not deserve to be there.
When I started a local, there was some animosity, but having known many members of other Fraternities did help us. But, it was very hard at first and then we affiliated with a strong and big national so we were on equal footings.
One thing is if the campus can handle it, which usually it can and the other thing that I always professed was that there are people on campus that do not want to join the existing GLOs. That is why we were so succesful with the local!
The very best in your endevor and it will as wptw said take time, maybe three to five years. Just do not let your dream go away!
