When monkeys get angry they throw their feces. So do humans but typically in a different form.
We throw our words, making them as hurtful as possible. When people use words to tear down the feelings and ideas of others, throwing verbal or Twitter type feces is what they are doing.
Instead, it is far wiser to remain respectful and seek common ground with those with whom we disagree. We then have a chance to persuade them rather than inviting their verbal or electronic feces in return.
