I imagined myself a non-Muslim who is living in western countries. Then I red Islam I found that it has a lot of benefits to myself that I want people to convert to Islam and possibly me. There are my self-interests:
1- Very low crime rate.
2- No one will run me over while he is drunk.
3- No one will still my properties.
4- No one will give an STD to my family.
5- No one will bully my children.
6- No one will discriminate or oppress me.
7- No one will deceive me.
8- I will not be fearful and anxious from wicked people around me.
9- No poverty and all people taken care of.
10- I will have free speech and human dignity.
Your answer may be but in there countries Muslims are the least civilized this is due to their leaders that the west did its best to keep them in power. You may say terrors they are the products of their leaders and the west extreme injustice and oppression. You may say but they hate Jews or Christians false teachings of some retarded people. How we can call people to become Muslims if we would put them down. You may say what the guarantee that Muslims will be like you. Free speech and democracy make people find the right prevail.
