With Luno that’s your only option. You can circle around a particular meaning but you can never really land. Not with respect to relationships like these.
The first sentence seems to mean that one is not allowed to notice and point out problems unless one has a solution. I have always hated that. Oh, yeah, well if you think that system is bad, what would be better? If you can’t improve it, don’t critique it. As if everyone should have all the skills or be silent, when in fact they might have crucial but incomplete skills for getting away from something bad. But then the second sentence almost seems to contradict this. Here it seems to be that one must simply no longer see things as bleak in whatever the area is. But that’s like telling a crying kid to be happy.
My emphasis: Now you’re getting closer.
Most folks deal with bleak logic by insisting it is not really logical at all. And the way they generally avert it is make the messenger go away. One way or the other as it were.
I think they also label the person negative, having no distinction, when it is convenient, between reacting negatively to negative things and adding negativeness to the universe where there was none.
Or they call him a “troll” who contributes here “in bad faith”.
