I think all right minded Sikhs are now waiting for all those community elders and organisation members present on that sad day at Derby Gurdwara to distance themselves from this persons comments and behaviour.
Inside closed doors a person may do as they please within reason and harbour whichever views he or she wishes. But to say such shocking, harmful, evil words in the presence of Guru Granth Sahib Ji and the sangat is unacceptable. I think if the leaders are serious about following the Gurus teachings, protecting our image, setting the right example to the next generation then this should be referred to the Akal Takhat for them to make a decision on, such is the gravity of what happened.
This would send out the signal that we do not adhere to mere words but those words speak through our actions. I think this is a landmark event. Nothing of this type has ever happened before from a U.K Gurdwara stage or indeed probably a Gurdwara stage anywhere. This will also prove to our brothers and sisters who feel alienated because of such people that we are not all the same. It will be interesting to see what step is now taken.
