Let's follow religion to the letter, just a few examples from the two books followed by billions of believers worldwide.
They both prescribe the killing of disbelievers (Quran 
8:12-13, 
47:4; Leviticus 
24:16); order their adherents to fight and enslave those with differing beliefs, a la ISIS (Quran 
9:29-30, Deuteronomy 
20:10-18); endorse wife-beating (Quran 
4:34) and the stoning to death of non-virginal brides (Deuteronomy 
22:20-21); order women to quietly submit to the authority of men (1 Timothy 
2:11-12); and mandate the public lashing of fornicators (Quran 
24:2) and the killing of homosexuals (Leviticus 
20:13).
Lovely stuff.
