Hi
Rebecca. I wouldn't worry too much about any negativity you find out there. David gets alot of fanmail and knows how much his fans think of him. Also, any actor gets used to some negativity - they expect it and I would imagine it's like water off a duck's back for someone like David.
I wrote to him a long time ago now - 18 months if I recall correctly and I received a very nice reply a few weeks later (a note and 2 signed pics). I didn't send a SAE either. Just how excited was I when I saw a handwritten envelope postmaked Manhattan Beach (where they film CSIM) on my doormat!
He does treat his fans very well and really appreciates them.
I must admit, I tend to steer clear of the negative websites. When I first joined Talk CSI, there was a fair bit of negativity here too (there still is at times, but not nearly so much), but I made sure it didn't put me off and I kept posting positive things!
If you are yet to discover it, there is a wonderful website dedicated to David, which is
davidcarusofans.com. Everything you need to know about him is there, plus there are great articles and pictures etc. There is also a Fan Forum, the
David Caruso Message Board where everyone is really lovely, and unpleasant negativity is actively discouraged.
Hope this helps.
