Is OTHER wrong in the post ? POST : He's the owner of a graphic design and marketing office and sometimes he puts out information to his designers that's not correct. For instance, he believes that a pixel is a set unit of measurement rather than changing in size depending on screen dimensions. He also believes that he needs to design internet graphics in 300dpi because this will make them sharper than 72dpi. So he'll tell us, for instance, to design something at 1080x1920, 300dpi.

Would I be the asshole for correcting him on these small bits of incorrect information? Or would it help him?
