These things are sins not because God decided one days to arbitrarily pick things out of the blue and call them "sins". They're sins because they harm people and and are anathema to a healthy, happy culture.
Then would you also agree that tobacco and alcohol are fellow antagonists of a “healthy, happy culture”?
>> They’re sins because they harm people and and are anathema to a healthy, happy culture.
I wouldn’t say that they are “anathema”, but they certainly aren’t conducive to happiness. If sin necessarily precluded hapiness, there would be no happiness.
We all have our weaknesses — we all have our sin of choice. For some, it is pictures of naked women — for others, it is pious pride in bashing people who like pictures of naked women. We all struggle with something.
Equating pornography with abortion with regard to their cultural consequences (or the level of evil required) is still ridiculous.
