I'm not sure what you're referring to, but I do not see how one can argue that Christianity is on par with Islam nowadays. Four or five hundred years ago, I'd agree (Islam was actually more tolerant back then), but today we don't see Christians surrounding the house of an eleven year old girl and demanding her death - at least, this sort of thing is extremely rare and isolated. It is idiotic to even make the comparison.
Religion must be destroyed if we are to survive as a species. Christianity will wither away naturally. Islam, on the other hand, must be destroyed by force. It is the only language these primitives understand.
