Thanks for asking this question my dear brother whever you are from. In Quran the Quote says "Kill every non believers that comes your way". yes I agree it is written. but.....but...you should read the whole context in which it was written.
Infact it was during preparation for a war against some clan.They had broken an agrement with Prophet Muhammed(PBUH). so Allah has ordered when going for the war. "Kill those non believers who comes your way".
This is the meaning those propagating hatred gainst ISLAM wants to tell.They always take some quotes here and there and tell Quran says to kill all Kafirs.
Even Quran says if the enemy concedes defeat protect him to a place of security.Will that happen in this era if your enemy concedes defeat will you leave him??
Just a smiple question when Krishna said to Arjun to fight against his brothers does that means all brothers should fight against each other?. it was for a different context right/...
