Islam is not seen with respect by some people because of:
Lack of knowledge about what Islam is
Often seen as not doing anything to protest terrorism
Misidentification (people view Islam as a race not a religion for all)
Muslims are often seen as being aloof
Our acceptance of Allah's(swt) will, is seen as being non-caring
Lack of interaction with the non-Muslim community
Love of the Ummah is seen as blind support of Muslims who do wrong
We are seen as being prejudiced towards non-Muslims
All of those things are the result of misinformation, lack of information and preconceived ideas. One of our biggest tools is to live our lives by the Qur'an show understanding and tolerance towards others. Set the example to show we are truly peace loving. We can not tell people what Islam is, we need to make the effort to show what it is. We can not control what the media portrays us as, but we can avoid being what the media portrays. We need to accept the fact that people will fear and be suspicious of us, until we ourselves show what we truly are.
In many countries we are the new kids on the block. We are stepping into a world were we are not the dominate leaders in the social structure. We need to live our lives in a manner that clearly sends the message we are not out to destroy any bodies life style. We just do not always wish to live all life styles. We need to stop isolating ourselves from our non-Muslim neighbors, we need to interact sufficiently so that they can understand that our seperation from some social pleasures is because we love Allah(swt) and not because we dislike any people. We need to keep a high visible profile so that people know we are Muslim and we are not a secret society that is plotting against them.
We also need to become aware of the fears and misconceptions others have of us. We need to understand why people have those ideas and do our best to prove that they are false. We also have prconceived ideas about non-Muslims. We need to understand that our misconceptions are also a prejudice and we need to act with knowledge not what we think.Above all we do need to make an honest effort to look for the good in Non-Muslims and let them know we appreciate the good.
