Because you have been brought up with nobody attacking your faith in atheism,using the well trusted lines atheists use about non- belief in a God etc having silent Christians not challenging your position or giving solid argumentation ,you feel threatened when someone challenges your presuppositions.
Your religion has been successful partly because it has required people to be continually taught to believe your book. Expecting people to turn up at least once a week, and have the supposed truth forced onto them, and feed them scare tactics to ensure they stay (the vast majority of people believe in the same religion they were taught to believe in, by their parents, their culture, etc – virtually none change their religion due to revelations). Christianity spread through the world using violence and not allowing challenges or arguments. The same can be said of most other religions.
Atheism is not the belief that requires groupthink, the one that shuts down arguments, etc. Atheism isn’t a single belief system, people disagree.
I’m not (and my beliefs are not) in the slightest threatened by you or your videos. Rather than threatened, they leave me bored, because they don’t provide anything new or revelatory. They neither provide proof of the existence of your god, or anything to make me question my stance. There are people of faith who do provide intriguing debates on religion/atheism who I enjoy listening to and they do challenge my views, the same cannot be said of any of the videos you’ve posted that I’ve watched.
