Why? It makes sense the way people are responding to the Tieflings especially after the events that happened in Elturel. The druids don't want the Tieflings there because of Kagha and the decisions she's made as the current Archdruid. The small adventurer party with Aradin just don't like the way Zevlor is.
Overall I expect to see more of it directed towards Zevlor and his band of Tieflings. Zevlor is also an exiled Hellrider (Deserter?) which might just bring more negativity towards the Tieflings.
Also, gotta remember that Baldur's Gate and Elturel don't exactly have the best relationship.
