You still haven't read and comprehended what I said. BAN ALL THINGS.
Not, let's allow TUE and exceptions to give some people an advantage, or not even need a TUE for a pharmaceutical drug (albuterol as an example, which my link and study clearly showed provides an advantage to cyclists while being used).
Then, anybody who has some condition will be excluded, unless they don't take any of the drugs altogether. That is the natural, fair and "that's life" method that should be employed. Will this exclude more people to be involved in competition? Indeed it will!
Changing the system and people's attitudes is impossible. The only way to deal with what people perceive as fair, is to make it as harsh and plain as possible, ban everything. There is no questions, no exceptions, and no excuses for anybody then.
That is fair and level.
