Theres something YOU have to understand. To tame a monitor, or any animal is a TALENT. That means, its something you have to develop. A skill. Its more about your ability then about how it effects the monitor.
If you had an understanding of monitors, you would understand, that healthy monitors can not only withstand lots of stress, but males seem to invite confrontation. In otherwords, males seem to enjoy a good fight. Healthy monitors are NOT easily stressed, you handling them IS nothing.
With females, you HAVE to understand how it effects the reproductive process and adjust to the condition of the female.
So you must first understand what a healthy monitor IS. My thoughts are, why don't people think about, ask about and are more concerned with WHAT A HEALTHY MONITOR IS, and how to bring that condition about. I think you and others should be asking more about that and not if handling is good, bad or indifferent.
So, yes handling IS bad, if you do not know what your doing. No, its not bad if YOU know what your doing. And No, its not a question anyone can answer if they do not KNOW your talent and abilities. Cheers
