I think it's a case that if the "self opinionated" cap fits wear it. But for most it does not. However I do think there are a very few that could wear that cap comfortably on certain subjects - and no I am not going to name names, I'm not that brave.
There are some subjects where my opinion would never change ( usually politics & religion), so I guess in those instances I am self opinionated.

So Harry and family are coming back!
I am also fine with strong reaction, but find it difficult if it gets too personal.
, you have made my day - SOMEONE WANTS ME !!, there are a few of us, not always obvious.

oh shoot!
