Wsalaam, wror I somewhat understand your intention, but it's not for us to say who's a kafir. It's a big sin to label someone with that term, which only Allah has the right to judge. We must change ourselves before we change others.

Oh and brother, don't argue, debate If you listen to others then you can also learn from them kana. Look at Dr.Zakir Naik for example or Ahmed Deedat, they don't shout or insult those who they debate with, they act in a respectable, orderly fashion.

As Allah Almightly says in the Quran, the true believers are: 'those who suppress their anger and forgive people', likewise, the Prophet SAW said: 'Allah is gentle and loves gentleness in all things. Make things easy and do not make them hard. And cheer people up and do not repel them.'' (Al-Bukhari & Muslim)

Khudai de mal sha.
