I agree with you as far as all of us having the freedom to choose what we want to follow, but after God changed me, lifting the vale allowing me to see truth, I just can't stop myself from wanting to share that truth with them. Honestly what kind of follower of Jesus would I be if I could just know what I know (what He has shown me) and just shrug my shoulders at the nearly 2 billion people on this earth that are in a system that leads to hell. For the record that goes for everyone outside of Christ, even those that attend Christian churches yet know Him not, I was one of these for nearly 5 years.
I just can't in good conscious say "you believe as you want and I'll believe what I want" in this situation. Not that I can change the world, or that I do anything other than try to submit to His will understanding that ALL power lays with Him alone, but I just can't agree 100% with that line of thought. I do think I understand what you mean though and agree, everyone has the freedom to choose what they want, the best thing and really only thing we can do is share His truth with as much love as possible. I also agree that many would leave if they knew more about what Islam truly teaches.
You know the thing that blows my mind more than almost anything, is how some feminist trip over themselves to defend Islam. I mean really?????????????????? Also how Jesus and Christians are attacked with such malice for anything even perceived, yet Islam seems to get a pass even/especially after terror attacks. Not surprising, and exactly what Jesus told us would happen, but still it blows my mind seeing it everyday.
