I think it is important to remember the order of events here. The entire game didn't jump down your throat ready to defend Sultan.
Han called you out an hour ago for not liking your Sultan suspicions after you expressed frustration that Han was sussing you without a stated reason. Then you started talking about how Sultan got "directly caught in a contradiction." Then multiple people went to source that claim.
When town finds a claim that looks like it's based on misinformation, it's very easy to get caught up thinking it's a manufactured scum hunt.
