that "only experts can opine" doesn't hold water.
Let me steel man your argument.
Premise 1. "Only experts can opine."
Premise 2. "Cougarboard posters aren't experts."
Conclusion: Cougarboard posters can't have an opinion.
I demonstrated how Premise 1 is false because one does NOT need to be an expert to opine.
Thank you for playing. Now scurry along.
