Well, sure, that's the straw-man definition of "God" that you can easily beat up. But unfortunately it's not really a universal theistic conception of God. Not even close. As most theists do understand that those anthropomorphic images of God are just that. Images: that we use to try and hold onto and relate to a "God"-mystery that is far beyond our understanding, but that we feel is fundamentally important to our own well-being.
Similarities and difference are all a matter of perspective. Like we humans, religions are both very different, AND very similar at te same time. Which, and when, just depends on from what point of view you're looking at them. Right now you need to imagine that they are all different, except that they are also all anthropomorphic and deistic. So that's what you're seeing. You don't want there to be any fundamental similarities that might lend my observations credence. So you're not seeing them.
