Breeding like rabbits to take over the world?
why does it seem islam is on a course to take over the whole world through birth rates?
Once again, this should not threaten you or anyone - its not like you are prevented from having kids.
As for birth rates, they are more linked to how affluent a community is - poor, less affluent communities have higher birthrates than the richer ones.
If you look at muslim immigrant community birth rates in europe, you will notice a trend of normalisation over time where they become closer and closer to the "native" birthrates, so this is not a threat and the best way to counter such things is to help poorer people become more affluent.
