I have to disagree with your idea that a large penis equals attraction or respect. I may go for admiration, envy or lust, but as DC pointed out early on, it would likely have to come with a complete package to equal attraction. If I see a woman with a beautiful figure and she is dumb as a sack of hammers or a complete bitch there is not only no attraction, but despite her beauty I feel repulsion.
As for respect I guess it depends on your definition. If I use my definition then I do not think anybody has seen my dick and found a new respect for me nor have I suddenly found respect for some guy sauntering through the locker room. Respect is something that needs to be earned by doing more than dropping your pants. I also do not buy that a guy who works out automatically warrants respect because of his body, nor a university graduate demand respect over a degree (I have met a few graduates who lacked common sense like I could not believe. I know people who did not finish grade 6 who are smarter than some graduates.) If you mean that somebody may think that a larger member would be better then this site is full of many such examples.
And on that note take NIC's advice and make a conscious effort to ignore those who attack your ideas unless they have something constructive to say. Don't bother attacking them back; it is pointless, but instead read and respond to those who offer you the debate you are looking for (though sometimes the debate around here does come in a manner that seems like an attack)
