Can you expect a person who is crap almost three quarters of his life to know that he is posting crap?
Of course, the answer is no.
Same thing as a person who is suffering from delusion.
Can you undo a delusional person from his views?
Of couse being the Boss, you can put such delusional cases in one corner or rather in one thread but I can tell you this for sure.
If delusional ppl can be put in one corner and they can shut the fuck up, then there could be a new found cure for such cases!
