I hate the "those extremists are not REAL members of my religion" rhetoric. We shouldn't forget that christianity also tells us to stone gay men to death, that slavery is good if the victims are from other nations, and that women should subject themselves to their husbands. The European slavers of the past were some of the most horrible people in history, and they were very christian too as they followed these rules to a tee. They did break the laws about respecting your fellow man, sure, but the inverse can be said of the christians who are decent people. They adhere the love thy neighbour rules, but break the rules that say that they should stone gay men. This means that the decent christians are much better people, but not necessarily more or less christian than the slavers of the past.
So if you are a christian and you feel bad by this association, I suggest that, instead of defending your relegion, you re-evaluate it.
