But your method is not valid or sound because you make a priori assumptions and then fail to support them. You also fail to consider the logical conclusions if your premises are false, you simply ignore them.KWED, because my way to first establish an argument is valid (different then sound), see what premises remain controversial (and already know 4 and 7 has not been substantiated in this thread), and then seek out to prove the controversial premises or counter a counter argument presented.
Presenting unsupported assertions and then saying you will support them later is exactly the same as simply refusing to support them. Which is basically what you are doing.
