I personally don't agree with the whole test tube baby thing because of the fact that it's not natural.  A natural birth comes from a man and woman having sex not coming for a science lab it's just not natural for a couple that can conceive a baby just fine.  But I can see the reason if people want to do it if there is some reason that they have a problem conceiving a baby.

Holocaust

If I was talking to someone that didn't believe in the holocaust i would call them stupid to their face because if they have never heard about it that means they don't our past history.  And if I were talking to someone about if they didn't believe in the holocaust I would tell them how do you explain the camps, the picturez and all of the survivors that have talked about it ???
