It's all "just our opinion".
It doesn't really make any difference whether we prefer to say things like "I think " or "In my opinion" or put in little strings of initials, or say it right out, as if we were stating it as incontrovertible fact. Whatever, it's just us, saying something we believe to be true, and maybe it is, and maybe it isn't, and maybe it's part of the truth
(The only exception to this being trollers, who say things they don't believe, just to annoy people - and they don't count.)
