Reread the thread. No one mentioned binding WITHOUT testosterone. No one even mentioned long term binding, 'til you broght up the 20 year example. And argument? I thought this was a discussion board.
Personal experience cannot account for more than well-known symptoms. Correlation does not equal casuation and the experience of one does not outnumber the experience of many.
Binding is not inherently dangerous or risky. Breaking down of breast tissue doesn't matter a bit, since it's being removed anyway. Consequently, the breakdown of my breast tissue caused there to be less to remove during my actual surgery and my reduction in size probably made my surgery a bit cheaper. The only way this logic is bunk is if someone is a keyhole candidate. This means you must have extremely small, very perky breasts, among other factors. Very few people can actually achieve this and, as a whole, those with such mall breasts typically do not need to employ such aggressive methods of binding, but instead can get away with frog bras, extra layering, etc.
One thing you did not mention is the risk of brochitis/pneumonia for those who bind too long and too tightly (also not binding properly...) and cause the lungs to be unable to expand enough to get rid of whatever gunk they accumulate. This is easily solved by coughing deeply every couple hours or by binding properly.
