Give up christianity:
1. you no longer have to struggle with the cognitive dissonance of believing that god wants you to believe in the facts of an ancient historical person/event at pains of eternal damnation
2. you no longer have to worry about the internal/legalistic squabbles of roman catholic/sedevacantist catholic/orthodox/protestants as to who is correct and therefore which ones are not hellbound
3. you can listen to whatever music or consume whatever entertainment you want without worrying about eternal damnation. if it's good it's good.
4. your family, friends, and other loved ones will stop thinking you're an ass hole.
5. you can still apply logic and reason to the culture and apply viewpoints and positions like cultural conservatism, pro-life, nofap, etc. as the situation warrants, and discard them to the extent the situation doesn't warrant
6. when you die and realize that you're reincarnating anyway you won't be shocked and caught off guard and will be less likely to end up being shot back into some shitty situation
