To me, having a strong opinion means I have thought about the problem space enough to understand what I believe are the important aspects and what optimizes them. Remembering to hold them weakly in the light of previously unconsidered or under appreciated arguments prevents me from becoming overly rigid.
I’ve been sent dick pics before, but being a lesbian they were very unwelcome. If someone sent me a painting of their boobs, though, yep—seems like that would work.
