IMHO, I don't see where stock investing of ANY kind.....no matter what the risk-benefits involved in the situation......should be included as part of any real discussion of Christianity.
IMHO, a Christian should definitely acknowledge and heed all but the first sentence of your post, which is quite simply an ad hominem attack against anyone who chose to invest here, vs. investing somewhere else in the stock market, or any other area of investment for that matter.
It would also seem un-Christian-like to judge another's motives......particularly virtually anonymous posters of which one would have virtually no real knowledge.....and continue to attack them on a regular, continuing and ongoing basis.
Sorry to get off on a tangent here. Seems to me a message board for religion would be the far more appropriate forum for a proper and more complete discussion of Christianity.
