"Or did I just say that I believed them because they were in a position to know, as with a doctor or a weather forecaster?"
There you go again - first denying you said it, then saying you only said it because somebody told you it was true - make up your mind.
No public figure has ever said that all British Pakistani makes were culturally implanted to have sex with underage girls - that was all your own work - you never reproduced anybody saying it, if they had said it it would have been liable to prosecution under the incitement to race hatred laws and whoever said such a thing is a racist, whether they are repeating something somebody told them or not.
The fact that you still defend it is indicative that you still believe it to be true, which makes you a racist.
It is little wonder you spend so much time and effort defending Farage's racism.
