Are white people using Birth Control and Abortion ending the Caucasian race?

Slowly yes.

This is happening because so many other groups who aren't white don't go to college very much where they become involved with the idea of using birth control or abortion to stop unwanted pregnancies. For example, being Muslim and being Catholic is similar in this one way of looking at things. So, Catholics and Muslims are both having what I would call a "population War" to see who can have the most babies worldwide.

But, the problem with this is this is ONLY going to create "God Awful" Wars between Catholics and Muslims in the future. This is inevitable that this clash will occur within the next few hundred years.

If you study history you can already see this coming right now.

Right now it is a Muslim population war taking place where Sunnis and Shias are trying to completely extinct one another. And because of this Sectarian war for control of the middle East I think millions are going to die between now and 2100 the way things are presently going. It's not getting any better in fact I would say it is getting worse every day.

But, at some point in the future within the next couple hundred years you can see this war of overpopulation by Catholics and Muslims will result (caused completely by overpopulation) in a war specifically between Catholics and Muslims and most Christians would eventually side with the Catholics.

And like the sectarian war now between Sunni and Shia Muslims this war is COMPLETELY caused by overpopulation, not enough jobs, not enough water, not enough tillable land, and the present wars are only polluting the lands and waters to the point where no one will be able to live and be healthy in Syria or Iraq or Yemen or Libya the way this is presently going. So, the number of refugees can only increase exponentially trying to escape their Hells to anything better in Europe or anywhere else it is better on earth either legally or illegally the way people do when death is the only other alternative.

In an anthropology class someone had a picture in a textbook of what the average person on earth would look like by 2100 or 2200 which was basically a light skinned African looking Asian looking person. So, this would mean blondes and Blue eyes and Red hair and white skin will become rarer and rarer worldwide. I can see this already happening around the world in moving towards the average of a light skinned African with Asian Features with dark hair and eyes with likely above average height  compared to now on earth.

So, I'm thinking ALL big wars in the future are going to be about Overpopulation. But, another factor here is that overpopulation will now start to collide with Global Climate change, raising temperatures in the Equatorial regions, ocean levels rising from melting ice, a coming or present Technological Singularity etc. So, there likely will be incredibly awful conflicts of all kinds at least for the next 100 years or so not just in the middle east but all around the world caused by people dying and people starving and losing jobs from all these events at once worldwide.

And in the middle of all this though it is more responsible to have less children to keep earth from nuking completely out of existence eventually, most people aren't educated enough to understand this and take it seriously yet. So, in the meantime white people being responsible by having less children will slowly start to fade out of existence world wide through interbreeding with other races and not having as many children as other races worldwide. So, the likelihood that the social responsibility of the White people of the world will basically cause them to somewhat extinct like Neanderthals eventually through this long process of evolution and interbreeding with other races worldwide.
