No, I'd say that this is the local religious community feeling disturbed that you felt that you had the right to wander in and start telling people how to do something. You said it yourself - that you went "to see if we could do something to turn students vulnerable to extremism to the Mosques and away from extremism". I count three fallacious assumptions in that statement:
1) You assumed that if you went to the mosque, then you would find people vulnerable to extremism.
2) You assumed that the mosque would have no existing plan or programme to counteract the problem, or that if they did have one, it would be ineffective.
3) You assumed that when you found people vulnerable to extremism, you would be in a position to successfully prevent them from turning to extremism.
Your final statement about "moderate Islam" - plus some of your other comments on the subject - makes it pretty clear that you didn't go to the mosque to try and prevent students from turning to radicalisation. You went to prove to yourself that your preconceived notions of Islam are right, and that you did your best to facilitate change, but since that change was rejected, you don't have to feel guilty about doing nothing further.
In short, your actions present the colonial values that inspire hatred more than they do diffuse it - that the White Man, the Educated Man, the Civilised Man, shows up with all of the answers and none of the understanding to show the masses how to live.
In a word, your actions were disrespectful.
