That won't help. Qur'an was also edited and altered over time.

Personally, I don't see a need for Christians to covert to Islam, especially for something so trivial. The religions are so similar already, and Muslims already believe that Jesus was a prophet and other aspects of Christianity. If a Christian has some deviating opinion from mainstream Christianity, I am willing to bet good money that there was already a sect or group that had the same idea a long time ago. There's no reason not to just consider oneself part of that group without having to convert religions and still hold Islam in high regard.

I know too many people that converted to Islam from Christianity for silly reasons like this that were already addressed by some other Christian group or whatever, in my opinion. I understand if someone is coming from a totally different religion and wants to be Muslim, that's okay to me I guess. But Islam and Christianity are already so similar, there's almost no point. I think some people just got caught up in the anti-Islamaphobia wave (good thing) and then fetishized Islam as the better or politically acceptable religion among Leftists that doesn't have similar issues to Christianity (not good, in my opinion).
