Why are liberals so quick to defend.....?

insults and bashing of Christians (upside down crucifix in a jar of urine for example) and declare it as free speech, yet turn around and say how intolerant and bigoted someone is when muslims are "disrespected"? Even on TV, when the police have a warrant to search a muslims home, first thing they say is "we'll be respectful". When searching anyone else's home...they tear it to shreds. What are they afraid of?
