If parents are okay with it and nobody is being hurt in a process then I strongly believe in the helping of a sibling. It can feel like a life saver and both will recieve just as much love from parent. But some parents might just be doing it to see what happens. This is practically abuse of the system, but for the greater good in general I do support the test tubing of baby.

Holocaust..did it happen?

If i was talking to somebody who believed  that holocaust didn't exist, i would say to them it did exist. Through all the tracking and systems of tracking how many people were involved in this genocide, it would be impossible to believe that it really didn't happen. The conspiracy would be too hard to follow and countries and survivors wouldn't just make up unrealistic stories of what had happened during the holocaust. It was a major part of world history and there is no way to go around it.
