Isn’t it important to respect the opinions of others?
Yes, it is. However, not everything is a matter of opinion. There are many principals and observations which are so well established, so well tested and so thoroughly investigated that there really is no conjecture: They are fact. If for example, someone wants to go around saying the world is flat, there’s no reason why that has to be treated as a respectable matter of opinion. It’s a factual matter, it’s silly and it’s just plain wrong.
