He wrote criticisms of just about every major western belief system - if you take into account his larger body of work, saying he was anti-this or anti-that just seems disingenuous. Much of what he wrote was criticism for its own sake because that's what leads to progress.

He wanted his critiques to hit hard; he wanted to be subversive. My reading, at least, is that he wanted to teach people to be critical of highly-regarded cultural norms and morals and his writings are essentially case-studies in exactly that.

He indeed had wide-ranging perspective but I think the one thing you can say is he was anti-Christian.

He even said a few good things about Christ but anything positive was along the lines that the Christians got him wrong.

He thought Judaism and Christianity kept the ubermensch down with their weakness (ironically). That's pretty clear.
