We are all politically selfish but we can try not to be- part of that comes by embracing the truth of our political views' limitations and confronting bad behaviour in our political circles. Ultimately, we can deal with it by being honest about where we stand and with whom. If you don't withdraw support for bad behaviour in your political spheres, are you not contributing to the problems of it?

Maybe listening to those who raise concerns about your political stances is how to strengthen and improve them and - if necessary- change them if they're wrong, rather than pig headed surety that we're all right and everyone else is wrong.
