Answer:
Absolutely not - the threat to Christianity comes in the form of education alone. Same with all the Abrahamic religions. Religions prosper in places of low education and low income.
It has been said that the internet is the worst thing to have ever happened to religions, as it allows the free flow of information between us. The numbers show this to be true. In a time when religions have more money and resources than ever, are building giant churches with million dollar multi-media systems, and spending fortunes on advertising, their numbers are in decline everywhere.
I always advise people to educate themselves, first and foremost. Find out if their beliefs are simply a product of their indoctrination or if they truly believe the claims laid out by their chosen religion. Study the history of that religion, including the atrocities committed by them, study thing like their views on science (Judeo-Christian religions ((Judaism, Islam, and Christianity)) all have a strong anti-science history which continues to this day, as science is a massive threat to religions), and then actually read the holy book as well as books from the other side of the coin like God Delusion, Letter to a Christian Nation, etc.
After this, you will be able to make a well-informed decision on your beliefs and feel good about it - whatever position you come to.
