I liken their posts to a situation I faced every time I went to a state or national convention of Professional Counselors. Those counselors in my area I knew who went to these conventions, became people I did not know. They stayed drunk and caroused around with people of the opposite sex and shared rooms back and forth. They thought they were safe away from home, no one would know, and they did their thing. I believe posters who post nasty/cutting remarks to others are like these counselors - no one will know they did it, so they do it.
Let your common sense determine the best candidate based on your conservative criteria.
Thank you for your kind and thoughtful post, Marcella. I do appreciate it.
