"I am curious, how do you reconcile internet trolling with christian/catholic ethics? I mean, does the golden rule not apply to the internet?"
You are the last person here I would expect to be asking that question!  😉 
I don't care whether you are Mr H or not, it is you who seems to have this fixation with those whom you allege post under more than one nick or should that be nic?
Regarding your last question asked purely out of 'curiosity' of course, as I am not a troll I wouldn't know. If you claim to be a good Catholic then you will know the answer yourself. If you do not claim to be a good Catholic or even a Catholic at all, I question your motive. It is quite common for lapsed and non-Christians to 'throw the Bible' at Christians when in their eyes the latter fall short in the practice of their Faith.
Incidentally, I have never claimed to be a good Catholic, I don't know where you got that idear from.
