As I said, just keep observing objectively. Do not obsess about the observer. Self-view cannot be dispelled by reasoning. During meditation it may fade away or disappear momentarily, but it will soon come back again if someone calls you an idiot.
There is no other way to eradicate self-view other than to cultivate constant, uninterrupted mindfulness of the realities arising and passing away in the present moment.
Other wholesome practices such as practising charity, observing morality, serving others, paying homage, studying the Dhamma, etc., cultivate the ground for insight meditation to bear fruit, but insight cannot be forced to arise any more than flowers can be forced to grow by pulling them up — just do whatever you can to provide the best possible conditions for spiritual growth.
