Everyone has an opinion on things. Some of the best discussions I have had with people is when they can discuss rationally their point of view. Here are my opinions. No facts or info backing up what I prefer. Just my opinion on which is better. Feel free to discuss.
Dogs are better than cats. My dog is super loyal and just plain amazing.
There are plenty of other things that people fight over. Beer vs wine. Hot dogs vs hamburgers. Or stronger opinions that have caused riots: Anti-vax vs Vaccination. Hillary vs Trump. Home school vs classrooms. Or even hands on learning vs textbook learning. God vs everyone else’s God(s) vs Atheists. Evolution vs Creationism.
All of us have an opinion on something. Sometimes our opinions are so strong that we don’t ever accept that we may be wrong. I am willing to have a healthy debate with friends or family as long as there isn’t animosity being brought into the talks.
