I don't so much see the strippers, honestly, though I've heard rumors. I suppose they don't come up to me because my characters are typically female. XD
Our guild doesn't allow certain PvP actions outside the battlegrounds, in the hopes of at least establishing ourselves as a haven of sanity amidst the jerks that have given Alliance such a bad reputation on our server, and it's seemed to work out relatively well. We're not the biggest guild, but we've been very careful about who we invite and how we handle things.
Dwarves and Gnomes share the same lands, actually, so yes, they're also hilly and snowy. And I agree with your brother and his guild. Tauren lands are beautiful - grassy plains with copses of trees here and there. Horde-side, that's probably one of my favorite places to be.
