Mankind must be positively and constructively wary of mankind, of their fellow man, of their families, of the members of their faith community, of their fellow-citizens.
Tariq Ramadan"If we had not created a set of people against another the world would have been corrupt", and "against" here means two things: Against in the fact that they are challenging you with their diversity, challenging your intelligence and to challenge is not negative, it can be very positive depending on how you are challenged.
