What should I say to my mom?

Whenever I have a discussion about the church with my mom she always brings this statement up, "it's not the church it's the people." meaning "the church hasn't done any harm it's the people that are branching off from the church that are bad." and things like the second coming isn't fear mongering or a cult tactic they just tell you to "be prepared because it might happen someday...shrug." What do I even say to that.
