Paul gets attacked no matter WHAT he does. With some people he just can't do anything right. If he were to save 1,000 people from a sinking ship he'd be criticized for the 2 he missed and then called a glory hog if someone gave him the slightest bit of credit. That's his curse for having the nerve to survive all these years.
You are spot on here. In other boards including the main newsgroups Paul is both reviled, criticized and nailed for every little thing. John worship is quite prevalent, but very little directed towards Paul.
The man was a Beatle! One of four. Whatever he does now has little bearing on who he was. And he still does some good stuff, it's not like he totally shat himself out in 1969.
Sure, like anyone he is open to being criticized, especially being in the public as much as he wants to be. But he gets a lot of petty and useless heat thrown at him.
While John gets a free pass pretty much all the time. That's why Paul worries about his legacy.
