You know much about the Islam and I hope that you can visit pal talk and find how Christians speak very, very, very badly about Islam, the Qur'an and Prophet Muhammad (Sallallahu Alaihi wa Sallam). I hope you can stop them. It's too much; I could not sleep last night because of the way they speak.

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

The errant and devious have been constructing so many sites that bring harm upon themselves due to major misdeeds and offenses they load on. But, our Prophet (Sallallahu Alaihi wa Sallam) will be safe from their harm, since polytheists in the Prophetic era accused him with bad attributes such as magic and madness. Also, they did their best to kill him, but in vain.
So, Muslims are required to boycott those sites. Then, it is not right to look closely at suspicions in order to refute them. However, it will be more beneficial for Muslims and Islam to construct new sites to refute the most important doubts and suspicions presented on those bad sites. We think there are some Islamic sites that deal with such issues.
Allah knows best.
