Ignoring flame war. (or perhaps edging one on :D )Wait, so you're saying it's good to be a hypocrite? And your logic is, if you've done it, it's ok to tell someone one thing then go out and do another? That's bullstuff. That's like saying it's ok for a murderer to preach nonviolence, or a doctor who smokes. I mean, once you're a hypocrite, your opinion on things becomes very dwindled. So if someone has done something but tell you to do another, and they themselves make no attempt to correcting their own wrongs, then you shouldn't listen to them. They know nothing of what they're talking about.
Only if you know of both of the situation. If you were to make a "Master Cheif vs. Gordon Freeman", if you support Master Cheif, but only play HL2, you can use their facts against them.
