Children aside, and excusing his horrible, horrible delivery, Sheen does raise some good points through all this about personal privacy and being allowed to live your life as you see fit. Piers Morgan made a good point that if he were Keith Richards, no one would bat an eye. But because he does a network sitcom...
On the other hand, he could certainly exercise some more discretion. And, you know... maybe pick a better/safer drug to abuse than cocaine. I'll never understand the fascination with that drug and its place as the "king of the mountain." It's fucking terrible.
Also, if he could pull off the partying while simultaneously NOT APPEARING TO BE TOTALLY BATSHIT INSANE, that might help people be more accepting of his lifestyle choice.
