You asked why people have to be ignorant and blindly religious; because they are religious due to habit and imitation of their fathers… You reminded that you have difficulty in some matters and do not understand the truth in them due to incompatibility of hadith… and that you do not have access to any trustworthy scholar about which you can speak about.
