Why do different regions fight amongst themselves but they're preaching love and won't practice it?
It's all because of hypocrisy. Hypocrites are everywhere. The only reason we preach love and peace and don't practice them is because we aren't conscious of our actions and if ot correlates with what we preach or utter. Some even believe to a large extent that they're better than the people of the other regions so the rule of love and peace doesn't apply to them and the bane of this belief is religion.
The radical jews are indifferent to the christians and hate the muslims. The muslims on the hand regards the christians as infidels and the Christians on the other hand regard them as unclean. The extent to which this beliefs are rooted in the minds of people is appaling and we'd find out that once religion is out of the picture we'd achieve peace and love to a large extent. Racism is no longer a major issue, the major issue now is religion and whi ch is Superior.
