The torah doesn't have anything against pagans because they are pagans. The torah, however, makes it clear that the values and practices that often comes from pagan religions are unethical and immoral.
Since the ultimate goal of the torah is ethical behavior(as outlined in it), so long as one doesn't engage in what it deems unethical and immoral, one is in good standing with the lord. Noah and Lot weren't great men... they were merely decent, but God saved them because they weren't that bad. I find this touching. It's not about being elevated religiously... it's about something as simple as not screwing your family, friends, or neighbors (strangers) over. Or at least in this lifetime here on Earth.
God cares about how you treat the other, and paganism whose practices and values/beliefs(which influences practices) that doesn't conflict with the torah's message is moral and ethical in its eyes. There are many paths to God and goodness. One doesn't need to convert to judaism to live out its principles either, so go forth and be happy in your religion so long as you treat each other ethically.
