Well obviously they will not preach any hatred when there is someone touring them. But it has been proved many many times that hatred against non muslims, especially jews is preached.
I understad that there might not be any hatred in Darghas since it is frequented by non-muslims.
And lastly I agree that Islam oes not preach hatred, but at the same time please don't deny all these acts around you. Also, majority of the outlawed organizatons happen to be Islamic.
