Think about it..
As a parent, i Have the right to use some force and make a child eat breakfast, go to school, dress decent...etc.
So why not use it for Islam?
Think about it..
A little force to make them become better muslims, Or eternity in Jahannam!!

At least you can try, So when Allah asks "what have you done about it?", you'll say:"I tried". If you didn't try, You'll be judged as an accomplice.
Bin Mas’ud, may Allah be pleased with him, once heard a man say: "He who does not enjoin good and forbid evil is doomed to perish."
Abi Bakr as-Siddiq, may Allah be pleased with him, narrated that the Prophet (SAW) said:"There are no people in whose midst sins are committed, and they do not change this situation although it is in their powers to do so, except that Allah will be near to overtaking them all with His punishment."
The Prophet"s (SAW) saying about disapproving with the heart only, that "it is the weakest form of faith", indicates that enjoining good and forbidding evil is one of the aspects of faith.
Abdul-Malik Ibn Omar Ibn Abdul-Aziz used to say to his father: "I wish that we would be boiled in a cooking pot if this would please Allah."
