My response to this kind of stuff is, that's one guy's opinion with the current morality of the time. The morality of another time didn't allow tattoos or mixed fiber clothing. Not sure about the clothing thing, but tattoos probably caused infection and were a bad idea. Similar to how eating pork was probably undercooked and a bad idea.

Homosexual intercourse is a higher risk for std transmission, so another "bad idea", especially back then. But we have some preventions for that now, so it's a bit safer. Perhaps it's time for morality to move forward to accommodate newer safety.
