Why is there no Muslims in Star trek? Because it's the future
Not sure what point you are trying to make with this one?
The modern world is different from the situation in the times of the star treks.
It is messed up to make a statement about Muslim people not existing in the future. This seems like you are talking about something happening to Muslim people that would wipe out the entire group. Hope this is not want you meant with this comment.
The future is what it is.
I have some bad news for you. By 2025 or earlier, Islam will overtake Christianity as the world's largest religion. So, I doubt Muslims would be wiped out in the future.
