If, however, you have no interest in my opinions why do you respond to them?

But I do have interest in your opinions Dave.
I just want to know why you hold them.
If they are based on no actual knowledge or facts, it makes a difference to how much attention anyone should give to them.
None, if they are based on just whims and prejudice.

I also want you to tell me why you think mine are wrong.
Can you?
If not, perhaps they are right and yours wrong Dave.
You need facts and knowledge to choose between contradictory opinions.
You seem to have none.
