Here is an example of my own actions towards Islam, relevent to your faith.
I have an old friend and a former colleague who are muslims. I have debated the existence of Allah with one of them but with the other I discuss his religion without trying to disprove it. This is because they are from different schools of thought and one practices a "different Islam" to the other.
My muslim colleague was the the one who instigated debates. I was a JW at the time but the way I would go about things still holds true to today and still happened with him after I rejected religion. He told me that Christianity was speaking lies, was corrupted, made claims about it and described how great Islam is. But upon researching I realised that he was propagating lies and was extremely biased following verbatim the reasoning of muslim apologists, did not know a thing about Christianity, misrepresented atheists and Shia muslims, hated the Shia with a passion, denied events like the Armenian genocide by the Turks and supported muslim violence, always attacked Christians and was evasive when his faith and religion was criticised, etc. He was an indoctrinated hypocrite who thought that his fellow muslims only did good and never did bad, condemned all critics, said there were no true ex muslims. He deliberately tried to indoctrinate me with lies and deception. This is the state of many many muslims unfortunately. He was dangerous so I attacked his religion and today he is not so religious but still in denial.
Alternatively, my old muslim friend is the complete opposite. He practices a different Islam. He is extremely humble and willing to accept his faults. He isn't indoctrinated and actually studies his faith and is a wealth of knowledge with regards to his faith. He can reason consistently. He doesn't condemn other religions based on lies. He condemns outright Isis, the Armenian genocide, Saudi Arabia and all those who he sees as not practicing Islam according to what he sees is the true faith as he believe it has been hijacked. He has no illusions of what proponents of Islam has done in the past. I respect him, his faith and do not attack his faith in the least.
Can you see my motivation in the one scenario verses my lack of motivation in the other? I don't believe in Islam in the least, but I can respect certain forms of it, and I will attack the ones that I do not respect because they are dangerous and they attack me.
