1a. MrLeRoy posted almost exclusively anti-WOD or pro-legalization articles.

As to "promoting drug use", that's a tough call. Stating that Congress doesn't have the authority, or that this should be a states issue, or that some drugs should be decriminalized, or that medical marijuana is a legitimate issue, that's one thing.
But going on and on, post after post, article after article, I can see where, maybe, one gets the impression that this is starting to look like "promotion".
If I said (insert NAMBLA activity here) should be legal, and I posted numerous articles about it, and I always responded positively to it in my posts, I daresay I'd be catagorized as "promoting" it.
Promotion of personal use/abuse is not political advocacy, and I've never seen him urge anyone to do drugs.
