Legitimate reasons for the crusades? Are you saying you’re trying to find legitimate, justifiable reasons for violence in the name of God? And you’re a Catholic? But wait… despite the Pope’s mistake (btw, I’m glad he finally apologized personally, thankyou Holy Father) his message was that in NO WAY can you justify violence in the name of faith. And besides, JP2 already apologized for the Crusades for the Church. Based on that, there is absolutely NO WAY that you can justify or legitimize the Crusades.
Furthermore, what are your legitimate reasons? How do you justify such a blatant disregard for human well-being and simply humanity in general?
Specifically, how can you justify the purge of the Cathars? Which, unless I’m mistakened, is classified as a Crusade. How can you justify Catholics killing other Christians to spread the Catholic faith?
And as to your statement, "Any religion that leads people to believe that there is any other way to the Kingdom of Heaven apart from Christ and His sacrificial and atoning death is false, evil, a deception of Satan. Any rudimentary comparison of Christianity and Islam would reveal in short order that the two are irreconcilable. Either one is true and the other false or vice versa. There’s no middle ground when you’re talking about revelation. If OUR reveleation is true, then their’s is a deception. If theirs is true, then we are truly misguided and deceived. This isn’t a matter of “you say toe-may-toe and I say toe-mah-toe.”. This goes against the words of the Holy Father and Church teaching. Remember, the Holy Father did state that members of other religions can be saved through their faiths. They do not reject God and are saved through Christ indirectly. Thusly, this means that these religions lead to God although they are indirectly using Christ as a mediator. That means that there is goodness and truth in them (if there wasn’t, how could they lead to God?) This would include Islam as well because the Holy Father did apply this to the major world religions, of which Islam is one (oh and for the record as I understand it, the Islamic faith holds Jesus in high respect as a a religious figure just not to the degree we do). Based on this, Islam cannot be evil, false or as you so put it, “a deception of Satan”.
And finally as to this "It would have been far more honest for them to have just said,“Yeah, we’re violent, so what?” "idea, it is rather limited of you to specify that to those of the Islamic faith. It is in fact an aspect of our fallen nature as the entire human race to be violent as a whole regardless of religious associations.
Oh yeah and the “Absolute Bilge” line was the best comeback ever, only once though. I would wager it loses its flair once repeated.
