AGuest “While I'm not sure I can agree with the first part of that, I certainly believe the last part. I am defined by who... and what... I believe I am. Isn't everyone? ”
Yes, we are all defined by what we believe, support, or the ideals we live by.
If our ego or self image is defined by a strong conviction or belief system, then we will feel compelled to defend it against any attack or undermining. As you say, this a necessary part of living in a world where people live by different ideals. The danger arises when the belief system does harm to society. Flexibility and finding common ground, can lead to peace. This board provides an arena where beliefs can be challenged and adjusted. On the whole it works very well.
