That kind of attitude is ok. Life can be lived by leaving out things we dislike and focusing on the aspects that strengthen iman. Good.
But is it ok if that person refrains to do dawa because he/she (personally) feels like he/she can’t explain/accept everything as it is in Islam?
What about raising children? I think it’s best to teach them what you know but after a point you should let them make their own choices about religion when they have such doubts/feelings.
Thanks for the discussion guys. It has been really interesting so far.
