Everyone is entitled to their own opinion. These opinions differ from person to person….and that’s ok.
Opinions can be based on a lot of different things: fact, belief, values, upbringing, history, education, training, experience, a gut feeling; or based on absolutely nothing at all!
You don’t need evidence to craft an opinion. It’s yours and doesn’t need to be justified by evidence, facts or anything other than that’s how you feel. And the crazy thing is how you happen to feel changes from day to day. Just like your opinion on something can change day to day, or hour to hour. Opinions aren’t concrete. They are fluid and forever changing.
Take politics. Sometimes Canadians elect a Liberal Government. Sometimes Canadians elect a Conservative Government. Other times Canadians can’t decide and elect a minority government. During an election; Canadians voice their political opinions by casting a vote for their party of choice. The party which they vote for can change from election to election. The change of vote represents a change of political support or political opinion. Opinions are fluid and change.
Evidence is completely different.
