You see... I was Christian for 32 years ... I've been Muslim for 6 years now and I have a very varied experience personally of many views... Aside from the fact that my beliefs are what they are, you have to admit that within modern day Christianity it is hopelessly impossible to unite everyone because there is no one belief system. There isn't even consensus among them on central basics like whether نبى عيسى عليه السلام ("Jesus") died or not. So yeah... I leave each one to his belief, but I do not tolerate attacking another's religion. Muslims all believe he never died but will die in the future, as all of creation must and will die, and all of mankind and jinnkind will be judged according to their beliefs, actions and intentions. But whatever you believe, don't argue about it.
