Assume that the person whom you are speaking with is actually against the slaughter but cannot voice his/her opinion because of the job. You want them to listen to you, so speak “to” that person with compassion.
They probably have to report how many calls they get on the subject. This does not mean that your words do not matter. What you say to this “living breathing soul” does matter. He/she may become an activist for the cause —- even if it is under an alias. He/she may quit the job in protest. We may even gain an insider to give us some information from time to time. Who knows?
Even if they seem rude, it may be because someone is standing over their shoulder or the call is being recorded. What you say still matters! If they become accustomed to hearing your pleasant voice, they may open up in time, so call back often.
“Once you encourage the thought of compassion in your mind, once it becomes active, then your attitude towards others changes automatically.” – Dalai Lama
