Usury (play /ˈjuːʒəri/) is defined either as the practice of making loans with excessive or abusive interest rates, or simply the practice of loaning money with interest. 
So...which one of the above definitions for usury are we using? Or are we mixing and matching them?
The one the Christian tradition upheld for some time, hence the "need" for the Jews. (Doesn't matter, since in the US you can lend at rates which anyone would consider predatory especially given their compound nature.)
Again, when is comes to certain sins, people go bananas about them. Others, they will bend over backwards, coincidentally, attempting to defend.
Let's count the threads on usury versus those on homosexuality. Since the former is much more widespread and basically endemic to our culture you would think it would get the most attention.
But it might cause Christians some actual pain to act like Christians. You know carry that cross they are always telling others to carry.
Good luck with that. No they will carry the Cross of paying their taxes, raising their kids, retiring, you know behave within the slightly more conservative and acceptable area of American cultural norms.
Oh, they fast or something, but can't be sure cause you don't talk about that.
You take my point. It's the same made earlier in this thread.
