WWLD your situation is sad and I understand what you are going through.I too am an atheist and the only atheist in my entire family.Unlike yourself religion was not forced on me,I simply followed it for a couple of years and came up with more questions than answers and the bibles answers were simply inadequate for me.I am still the only one who does not believe but I do not make an issue of it.We generally stay away from the topic of religion but when I am challenged I do stand up for my unbelief.I dont suggest you challenge your parents on the reasons for their beliefs since they seem to be very deep rooted and traditional regarding their beliefs.Any challenge would just create more friction and cause you more grief than is necessary.When you are old enough and are given some wriggle room from their grasp then and only then should you defend your unbelief if challenged.They will have to decide whether to respect your non belief or not,hopefully they will and leave it be.Good luck
There is nothing people will not maintain when they are slaves to superstition
