I am not a Christian. I describe as an "Asatru leaning agnostic" or maybe "a practitioner, if not a believer, in Asatru". Still, I'd I have to say that Christians make far better neighbors than many another group. Yeah, they have their bad apples but the comparison between Christians as a group, at least in the Western world, and Isis or the Taliban is beyond ridiculous. Part of that is simply a matter of civilization. People simply behave better in the civilized world than they do in the more barbaric regions. However Christians in the civilized world try to spread civilization. Groups like Isis and the Taliban try to spread barbarism. Apples and dark matter they have so little in common. I have yet to meet a Christian who believes I must die for being asatruar (well, leaning that way anyway). They may try to convince me of their belief. They may be concerned for my immortal soul. But they do not say I should be killed for not believing in "the god of the book." How have ISIS and the Taliban weighed in on that? Is, perhaps, the choice they offer Islam, Dhimmitude (for Christians and Jews--"people of the book"), or death?
The Crusades you say? Well, leave aside that the Crusades were quite a few centuries ago, you might want to look more deeply into the history behind them. It was a lot more complicated than simply wanting to kill the infidel in the name of Christianity.
As for folk like the abortion clinic murderers and the like that are often paraded about as examples of how "Christians are just as bad", you might want to consider the religious leanings of the people who investigated those crimes, the people who caught the culprits, the people who tried them, the people who convicted them, and the people who punished them. Simple statistics suggests that the majority of them were some flavor of Christian.
How about ISIS or the Taliban? Same thing going on their? Violence in the name of their religion being punished by their religious peers? No? Then would people stop with the false comparisons?
