Isn’t it?I realize that is the standard thought. I don't necessarily agree, but even if it were true... the behavior is not Christian or in accordance with the scriptures.
Matt 5:29-30:
29 If your right eye causes you to sin, tear it out and throw it away! It is better to lose one of your members than to have your whole body thrown into hell. 30 If your right hand causes you to sin, cut it off and throw it away! It is better to lose one of your members than to have your whole body go into hell.
The mob in Alexandria saw Hypatia and the library as leading people to sin, so they tore her and it out.
