Islam came as a religion for all mankind and at the same time Islam does not force mankind to enter Islam.
If you enter Islam by force then most probably your belief will be weak and not strong.
I also repeat the following no need to be a non Muslim to be a good person, but Islam will give you the answer for many questions which you might ask.
Please remember Islam is a choice which you may or may not select.
Have a good day Nic and I wish if you have gone through the links I put.
