Salva,
I haven't really read much into your threads of the past so I will treat this objectively.
I live in brisbane. I have lived in Brisbane for many years and can't stand the bonkos. Absolutely hate 'em in fact. A mate of mine asked me the other day to rate all the clubs from 1 to 15 and luckily the broncos came in 14th. Only because of Manly though. I am a campbelltown boy originally so hating Manly is in the blood. But anyways back to why they are hated (by me at least, though in no particular order)
1. The Super League war - they started it, no questions asked. I can see the frustrating reasons behind why it happened, but the sneaky, underhanded way things went down with Ribot & Johns going about business was disgusting.
2. The South Qld Crushers - not entirely the bonkos fault, but they did no favours toward them in terms of junior base recruitment. I was finishing high school at the time and knew a few promising footballers who, because of their own club associations, couldn't talk to the crushers - it was bonkos or nothing.
3. The (once mighty) BRL comp - when the bonkos came in it destroyed the winfield cup in Brisbane. Brothers won in '87 to a huge audience but as soon as the bonkos picked the eyes out of every local team the comp went to sh*t and has never recovered. The bonkos didn't care less about the seniors, but managed as quickly as possible to stich up all junior ties (refer point 2 for effects)
4. Cause in the late 90's they used to crap all over the magpies. Bastards.
I think all in all you have to accept that the broncos are a hated team. Including I would suggest 3 out of 5 league fans in Brisbane. Remember the comp has been running for a lot longer than 18 years, so there are many people in Bris, including myself, that have followed another team and will always follow another team. You probably just need to realise that they will only ever be held in the same regard as the rorters and (wo)manly by the majority of the comps supporters.
