It is very clear from what you’ve said that you haven’t used it :) I have browsed it when it was active and I was very pro tor. You’re making a lot of assumptions that simply don’t hold for silk road.
I was playing devil's advocate, but agree there is more culpability to a seller if the drug overwhelms your ability to make the choice in the first place- however a lot of very illegal drugs do not do this. More so if you're using emotionally manipulative ads and selling methods as the alcohol and pharma industry do.
