Is it a sin to be older than twenty (20) in Hollywood!!!?

I have had many conversations and attended many forums that champions Ageism in Hollywood but thus far nothing has happened. We need to make things happen!!! I for one is sick and tired of being sick and tired of all the roles going to either already famous, famous actors or new borns or comedians, or American Idol contestants or Reality TV shows participatns!!! Let's change the system!! Show Hollywood, we are alive and Kicking!!! Banning together and making our voices heard can be a start to saying, "we are not going to take this lying down!"" What do you think? Is this my imagination or what? If I am wrong I stand corrected, share with me to convince me and others, otherwise. Help!!!
