They were a response to over 400 years of brutality and forced conversions.
First of all, forced converstions is probably one of the most hilarously mythical claim made about the Muslims. Under circuimstances, Muslims even discourged converstion to Islam, as it was more than a religious thing. non-muslims were taxed more heavily, however they did not need to serve in the army. There were preasured conversions and encouraged conversions, however, I believe the very idea of forced conversion is somewhat doubtful, given something called human nature.
Second of all, Crusades were nothing but raids with a better description in my opinion. It was fought for power and profit.
The Muslim horde destroyed nearly every church in Byzantine,
"the muslim horde" is a word which clearly shows your biased view. Also, you might want to show credible evidence before making such claims, given that it is the first time I've ever heard this.
what we call Turkey today.
It was never called "Byzantine" during it's existence.
Many of the Greek texts were in jeopardy,
Nope. Muslims preserved such texts actually.
like Plato, Socrates and these were later taken back from the Muslims - many like the library at Alexandria, Egypt were destroyed.
There is no evidence that libary at Alexandria was destroyed by the Muslims.
Muslims had built libaries, laboratories, hospitals, clinics, univercities, even observatories and other scientifically important buildings. For example in Baghdad many were raided by the mongols, resulting in a loss of great amout scientific work. Christians burned muslim books in public squares in Spain.
Also sacked was the Christian holy city of Jerusalem, pillaged and destroyed by Muslims.
Umm, yeah. So?
It's called warfare. Why point out Muslim atrocity when everyone did the same? In fact, I think, no one claimed not to do so.
