Non-Catholic Christians, what does your pastor usually preach about on Sundays?

I came across this a href="http://www.tonybartolucci.com/Sermons/TiberLight.htm" rel="nofollow"http://www.tonybartolucci.com/Sermons/Ti…/a and found out that this guy spent 12 weeks going on about what he thinks is wrong about Catholicism. Is this normal? Or how commonplace is it to talk about others' beliefs?
