OK, and? You don't hear any warnings that they should stop because it might cause a violent backlash, do you? No threats of beheadings or bombings if they keep doing it. And there is nothing in the NT that calls for death, beheading, dismemberment, etc. for those who burn, flush, tear up, or otherwise "disrespect" the NT. Seems that there is only one religion that calls for things like that.
