Excusing bad behavior never gets anywhere either.
If watching or displaying pornography is socially acceptable behavior, walk down the street browsing a copy of some pornographic magazine and check out the reactions you will get. Try and give it to a child with their parent present and see what type of reaction you will get. Watch porn in broad daylight in your front yard.
Don't know where you are spiritually but if you are actively looking at porn and think it's okay, it's probably safe to say you are a dead corpse spiritually speaking for the Holy Spirit alive in you would be deeply offended at this. Whatsoever is good, lovely and pure, think therefore on these things. I appreciate your honesty and know you are speaking for many people (otherwise girlie clubs and all these magazines and such would not be such a huge industry) but if the Bible is true (I believe it is), then God has written the Law on your heart and you know what many on this site are saying to you is true and that is that this is not a harmless sport or indulgence, not to you or to those (even those willingly) engaged. What father wants his daughter to grow up and be a porn star or porn mag editor and so on; it's because we often don't want to be "intolerant" of others yet deep inside we know this is not good. I hope you will pray and think about it. This subject is very sad for me. God bless you.
