Thank you for pointing out flaws of ambiguity in my comment.
> If they are mentally unwell, it doesn't make their suffering any less real does it? I admit I am biased as someone with a mental illness, I wouldn't want someone to disregard my opinion based on knowledge of my illness.
I meant only to reference the variations in tendency towards certain mental behaviors (such as accurately assessing reality, or taking responsibility for emotional responses) that exist among people. I gave an example of the "mentally unwell" to illustrate that this spectrum exist, but all parts of the spectrum are worth considering.
As an aside, and to hopefully show I'm not brushing with too wide a brush here: people with mental disorders are, sometimes, actually far better (at, say, having an accurate view of events) than people who don't have disorders, because they have [in the course of learning to cope with their issues, have also] learned to understand and correct for flaws that we all have.
I did not mean to suggest that people with mental disorders should automatically have their opinion/experience/claims discounted!
We should evaluate each situation individually. But there are clearly cases where a person's claim of "being hurt" should not be allowed to influence certain decisions, or policy, regardless of their overall mental/emotional functioning.
