Wait, he's a dudette? jk. If he doesn't want to get taken to task for an adult version of "I'm gonna take my ball and go home" then he probably should just take the advice he wishes, and shrug off the rest without resorting to a modest temper tantrum.First of all he is not a "dude".
To my reading, it wasn't so much an incessant sales pitch; more a series of snippy responses by the OP to people actually trying to help him with the issues he raised. But everyone has their own comfort level when dealing with the internets.
