Can you provide a definition for this? I'm fucking sick of people going through this process:
1. Struggle to understand someone's problem.
2. Give up.
3. Blame the victim.
If you see a problem, fix it. But nothing in your comment was at all helpful for the same people you were criticizing. This may come as a shock to you, but people struggle from different problems than you do. Some of them may seem easier to you because you don't experience the same thing.
In context, "weak willed" referred to the fact that parents let themselves be convinced that their children had ADD when they should have known that they were being sold drugs that were merely performance enhancers.
Overall your post comes across as an angry rhetorical rant, while the original post had some interesting content.
The "solution" that I imagine the poster would propose is to recognize that Amphetamines offer advantages to almost anyone, and that either we should be honest about their use as performance enhancers, or find ways to distinguish between a genuine need for them, and their use for enhancement.
"suggestible" comes to mind, but I don't think this is really the same thing.
And if the poster really believes that the parents are weak willed, I don't think that saying so can be considered as failing to use reason. In fact censoring oneself to use adjectives that carry less negative connotations, is a violation of reason.
Side note: The poster's username is 'negativity' after all :-)
