The practice of blasphemy is only useful if you are deconditioning yourself from religious indoctrination, and thus will find the act shocking and liberating. Otherwise, it really serves no purpose other than to try to be edgy and “dark.”
In some sects of Tantra, for example, they purposely break the religious taboos of Hinduism as a way to gain power, but it only works because they were raised in that religion. A Western person, would not gain any power by breaking those taboos because they don’t mean anything to them.
For a non religious person such as myself, desecrating a Bible would be no more emotive or effective than ripping up a newspaper.
