So how can we discuss when no one even understands the substance of Riba. Well since no one came forward I'll throw something out to begin with.
Question for the thread opener. When you say how can we avoid interest do you mean how we can chose Islamic alternatives in the society we live in or avoid it all together?
The Islamic alternatives could very well be an answer. That's what I'm seeking; to learn what the alternatives are. As br. Cold_Fire pointed out the things he does to avoid indulgence in Riba as much as possible.
As for your previous question, I personally believe Riba is Riba. Significance of time (Ancient vs. Today) does not matter, because we have been foretold of a time when it would be unavoidable for us to abstain from being involved in Riba (as stated in a hadith).
But, I suppose the goal of this thread, and core of my question is What can we do to ensure that it is minimal, if even that.
I hope that clears any confusion..
