Flexibility in Preaching the Gospel

I received the following request on youtube:

Would you, as a gesture of friendship and in the interest of a discussion in good faith, edit your profile so that it does not reflect your aggressiveness towards Allah, the Quraan and the Muslims? Thank you. 

My profile reads as follows:

 I believe strongly that Islam is modern day Nazism--where Der Führer has been replaced by Allah. My approach to combat this false religion of Islam is to show that it is logically impossible.

We must show Muslims, that when the Bible and the Quran are compared via unemotional and honest academic examination, the Quran, which adduces the Bible as evidence of its validity (Surah 10:94), cannot stand. Thus, the only intellectually honest reaction to the Quran is to reject it, and Islam with it as the Bible calls them accursed:

"But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed! As we have said before, so I say again now, if any man is preaching to you a gospel contrary to what you received, he is to be accursed!" Gal 1:8-9

My response is that I will pray about it since my goal on the internet is to preach the Gospel of Jesus Christ and to excercise my spiritual gift of teaching (Eph 4:11). If the above statement prevents this goal, then it should be changed per 1 Corinthians 9:

 19For though I am free from all men, I have made myself a slave to all, so that I may win more. 20To the Jews I became as a Jew, so that I might win Jews; to those who are under the Law, as under the Law though not being myself under the Law, so that I might win those who are under the Law; 21to those who are without law, as without law, though not being without the law of God but under the law of Christ, so that I might win those who are without law. 22To the weak I became weak, that I might win the weak; I have become all things to all men, so that I may by all means save some. 23I do all things for the sake of the gospel, so that I may become a fellow partaker of it. 1 Cor 9:19-23
