Yes, a controversial pastor's deportation is a sign that religion will be wiped out of Africa in the next few hundred years. Elected leaders in Africa do not want religion, because it gets in the way of government power. It also is in opposition to the corrupt governments that exist in much of Africa. The leaders want to protect their power and to do so, they will wipe out religion.
Religion as we know it today may very well be wiped out in the next few hundred years. Religion of today is very divisive and go against what many of us "know" in our hearts. They may be replaced with a new type of religion--more inclusive, more open and more universal.
There is no way that religion will be wiped out in the next few hundred years. It will never be wiped out at all. People are always searching for meaning from a higher power. Many people know that there is some power out there beyond us, and they will never stop searching for answers.
No, religion will not be wiped out in the next few hundred years because it is a part of human nature to want to believe in something higher. Religion is embedded in our DNA. While there may be setbacks here and there, ultimately, people will want to worship a higher power.
