Yeah, Mazara (together with Marsala and Trapani) are not really top teams, due to lack of money and valid sports centers. But their supporters are great, they do deserve better.
I've found these two websites:
http://palermo.theoffside.com/ and
http://www.football.co.uk/palermo/index.shtml . The first one seems to be very updated, passionate and well done
I didn't know it until 3 minutes ago to be honest
Our official website can be helpful as well:

Don't worry about pink, it's the same old story, wherever you go, anywhere in this world, including Sicily... but that's what makes us so special and we're proud of our colors
You can see our brand new shirts here:

As concerning supporting Palermo instead of Juventus or other strong teams we call "strisciate" (which is like "striped", as Milan-Inter-Juve all have stripes, but with a negative value): well that's one of the major problems we have to live with even here in Sicily. Being in Serie B or C for 32 years made people forget about their city club, a lot of people who are now 30-40 y.o. or older currently support the "strisciate" and try to make their children do the same. That's mainly because men tend to stand on the winning side so that they can celebrate something every now and then rather than stick to their homeland, suffer for it, cry for it and be proud to belong to that city/town... isn't that what sport is all about? I think it is, we do our best to make people change their mind and we're (slowly) obtaining some result
P.S.: thumbs up for your uncle
