Not sure why all the doping issues have changed your love for the sport, after all it's always been a problem. Or did you just prefer it when it was a given that everyone took speed so it was ok?
For me, doping is the reason I've never taken to cycling and I just don't get the attraction of watching a bunch of druggies on a bike? Athletic competition should be about pushing the limits of the Human body, not extending them through artificial methods
