Ann Miner Collection: "Life is too short for bad books" May you find justice.

Okay, I got through chapter one, all the while going "Whiskey tango foxtrot?" The author talks a lot of smack on the Roman empire. Like A LOT. I picked up this book because I wanted to know more about ancient paganism. I could be wrong because I haven't laid my filthy little raccoon hands on books with the information I'm looking for, but I am under the impression that the people who referred to themselves as pagans first were the celts. So why are we talking about Rome?
I get it, Greece is cooler. So are their Gods. But! Istanbul was Constantinople. You can't go back to Constantinople. I just want to know why you'd spend all your time learning about Rome just to write books about how much you hate Rome. What a miserable existence!
It also kinda came off as a put down to The Old Gods and why Christianity took over and is definitely superior. Kinda like I should be shelved next to A Case For Christ. Which, more power to you. If studying the fall of Rome solidifies your faith more power to ya! However, putting people down who are different from you isn't exactly "loving your neighbor as yourself." The Old Gods are dead to you. Stop taking pot shots.
On a personal note, some of my religious friend are modern pagans. I picked this up because I want to understand them better. Talking smack on someone else's Gods is exactly why people assume I'm hateful when they meet me and I say I'm Christian.
