Personally, nothing. I haven’t seen any KKK activity, and I’m Jewish. But the reason I haven’t seem them is that collectively as a society the US, a predominately Christian country, did a lot. See https://en.wikipedia.org/wiki/Ku_Klux_Klan…,https://en.wikipedia.org/wiki/Ku_Klux_Klan#Resistance_2, and the judicial bankrupting of the UKA (https://en.wikipedia.org/wiki/United_Klans_of_America).
On the other hand, moderate Muslims are doing things about ISIS/Da3esh. Most of the soldiers fighting them in Iraq and Syria are Muslim. Most of the Egyptians fighting them in Libya (http://uk.reuters.com/…/uk-mideast-crisis-libya-egypt-idUKK…) and the Sinai are Muslim.
