This is WELL beyond the realm of anything that an internet forum can give advice for. It's the behavioral equivalent of trying to give advice to someone about a dog who is having some serious medical problem. The ONLY responsible answer is 'seek professional help'. IT sucks and it's isolating and i'm sorry but that's really all I have.
Yes, because obviously writing a sarcastic post will make more people want to help you...You posted yesterday...many people take time to view the forum or don't respond until the weekend when they get time to post, because, you know, they work and stuff and aren't glued to this site. Some of the views you're seeing may be from lurkers or people who have no experience in that realm. The person who offered advice is a professional dog trainer and experienced with those issues.
But yeah, aggression issues, especially with a bite, are often beyond the average dog owner's capabilities. You should probably contact a professional to help you, or work with a rescue that is willing to rehabilitate dogs with aggression issues.
