ps: I asked you for a valid argument, not trying a last ditch attempt at asking for a source on something you know will take me more time than i want to invest into a conversation devoid of interest considering the party i'm discussing with has no argument to begin with, so before you bitch and moan why don't you give me a source on everything you said, if you provide i will give you a source too or i will be proven wrong. Doesn't feel good does it? You invalidated everything you said so far until you do. Best of luck
