yes you may not agree with it, but im sure Islam has converted so many non believers to worship our master. so rather than trying to label other religions good or bad , just be happy that it’s spreading the gospel of our creator.
If you really think that Islam conversion is spreading the gospel try spreading it (the gospel) in places like the home of Islam, Saudi Arabia and like Pakistan, especially among Muslims and see where that gets you.
The spectacle that you mention may be big but I doubt that it will be what you want.
It won't be the peace and harmony that people say it is.
