"The only reason for believing that is because you were born in y"

The “the only reason you are a christian is because you were born in the country y/x” argument:

1:If you use this argument to disprove the position of the believer than you just committed the genetic fallacy

Just because you believe in christianity only because you were born in the us,or Romania,that does not mean that christianity is not true.

2:most religious people that claim to be in the religion x or y because that’s how they were raised aren’t really the religion x or y.
