Chuckie. WTF.
I can already tell from you 'arguments' and increasingly personal comments on this thread that this is not going to go well, but i just can't leave it.
How, in the name of all that is rational, do you expect people to believe that a guy is not a good parent if he watches porn? That he should not be allowed to spend time alone with his child because his 'perversion' (as you clearly see it) will somehow corrupt?
Assuming that you are correct that the guy is addicted, and was addicted (to you bitterness) throughout your marriage, did he once ever expose himself to your child? I think that if he had you would have mentioned it.
Now, you need to prove not only that he is addicted, but that he will expose his child to porn and that this exposure will be damaging; not just by your standards but objective ones.
I sense that you have long been angered by this mans liking for porn and you are determined to convince everyone that it makes him deviant.
