Question: My family keeps trying to re-convert me. What should I do?
Although this seems to happen more often with young people living at home than adults, atheists of all ages can still face religious families who want you to "return to the fold" to renounce your atheism and become once again a religious theist like themselves. The first thing to understand is that they are not doing this out of malice no one who tries to convert you to their religion is doing so because they hate you or wish you ill.
This may seem like an obvious point, but remembering that their motivations are sincerely good may help you refrain from taking it personally. It does not, however, mean that you should accept it without complaint or objection quite the contrary, actually. There are all sorts of things which people might try to do to us "for our own good" but which we have the right to reject.
Because they are your family (with whom you presumably wish to retain some measure of good relations) and because their motivations are good, your rejection of their efforts should be framed accordingly. You need to be firm and clear that they are welcome to ask you questions which will make you think; they are also welcome to ask you questions about what you think and the doubts you have. That does not, however, given them license to be disrespectful to what you believe or to act as if you were some sort of target for evangelization.
If you are young and living at home, your options will be limited and you may have to put up with a certain amount of such proselytizing from your family. If you are an adult and independent, however, you may have to choose between putting up with your family's behavior and causing the rift between you to grow wider. You may, for example, be faced with the possibility of simply walking away from your family, perhaps cutting a visit short by simply leaving because you are no longer willing to deal with them.
That would be a harsh reaction, but it might be all you are left with if they are unable to respond to simple requests that they show you more respect and consideration. In the end, that is what it comes down to: respect and consideration. You need to show them to your family by not trying to constantly de-convert them, but they must return the favor by not constantly trying to re-convert you. If you can all be respectful to each other, you can continue to have good relations. Otherwise, the relationships may not survive.
