I think us 2 has been eliminated from this forum.
Allow me to ponder for a bit...
As I have posted earlier, people like us 2 exhibit themselves because it gives them a tweak to do so. It is a sexual addiction. The brain is the largest and most active sex organ in our bodies. It is the organ that produces the rewards for carrying out various activities.
[There is a whole spiritual and theological side to this and I tried to address it but that got messy so I erased it.]
Why do some become fixated on carrying out perverse sexual activities for a tweak? I don't want to completely absolve anyone by saying they are a product of their upbringing but clearly, those who are abused or inappropriately introduced to explicit material have had a stumbling block put in front of them. Those who have been stumbled can either recognize they have been tripped up or they can wallow in the filth they have stumbled into.
Not every perverse person is a victim of abuse. Some have come into their perversion on their own. But I dare say that those who are young and practicing perversion are doing so because it's what they were taught. They are then set up for a life of struggling with it or just giving into it with abandon.
Where does us 2 fit into this? I don't even pretend to know. However, we have to set limits and say, "You aren't bringing your perversion here." which is what has been done in this case. We can't negotiate nor argue with someone who is bent on trying to get us to validate their perversion. All we can do is block them out and pray that the Holy Spirit will break down their hearts.
Thanks for letting me vent.
