In truth, when someone has a firm belief in anything, there is little chance that anyone can sway them to another point of view. I used to teach my students that it was important for them to be able to SEE another’s point of view, even if one does not AGREE with their point of view. Granted, this is something that actually takes practice.
Regardless of who I vote for, I can understand, even though I heartedly disagree with, other peoples’ opinions and thoughts regarding who they choose to vote for. Being able to see, even understand another’s point of view, is a very useful skill to have, and frankly, it makes arguing with someone who is a complete lackwit (of which there appear to be an inordinate number of here), a lot of fun.
