Rule of thumb in the forgotten realms - See Drow = kill or run away
I am unsure a farmhand or blacksmith is going to go for a quick chat with a random Drow to determine his religious ideology on the off chance he/she lands in the 0.01% of "one of the good ones". A solitary Drow would almost certainly be a scout to size up a village or towns defences before a raid and any accompanying non-Drow would be assumed slaves or allies of Seldarine Drow.
I think the current Drow conversations are okay but the likely reaction would be a mob of clinkers charging after you with pitchforks. A disguise would be pretty much mandatory for free movement.
