Could you help me with my speech on intolerance?

I have lived long enough now to understand such things as intolerance of a person or group of people based on any one thought is simply a waste of time.Most people base there prejudice (and that is what this is) on the fact that they think they are better than those they are pointing there fingers at.Its a lack of logical thought such as in gang mentality where if you wear blue and by accident go into a territory where Red is the gang color you can die for this mistake.Yet if you take each of these people and put them in a room where you can actually talk to them (I do not mean prison cell) you will usually find they all have the same feelings but just in reverse of the other person.It is a lack of intelligence and a lack of communication that allows these things to happen.We are all people we all love-hate and bleed the same color blood the only difference is the ones we allow to grow out of ignorance and fear of the unknown.
