We are at the point where opinion B is allowed to exist. We know it exists because we have a link to it. We should not go toward the point where it cannot be analysed in any way at all without everyone immediately assuming that you agree with everything in column A because you analysed one part of column B. But that tends to be how people react to everything.
I am long past the point of thumped awareness where I would think you pointing out a flaw with point B automatically means you 100% agree with point A.
