Duh? That's completely subjective. Also, do me a favor. In about 30-40 years, when you're no longer in your teens, tell me you'd like to be judged on the way you acted as a kid. It's not exactly a novel idea that people can change over the course of 50 YEARS. That same logic should also apply to Barack Obama's drug abusing past. But since they wanted to bring up these things, let's bring them up.
No. It isn't subjective. Bullying someone else is far worse than taking a substance that only affects you.
