I sometimes feel that when I express myself with an opinion, or on occasion when I vehemently disagree with someone over a matter or subject, my ideas are deliberately invalidated by the other person because they see me as mentally ill, (sometimes saying as such).
I have the impression people sometimes misconstrue the behaviour of a person being passionate. Occasionally a label will be projected upon you which can be used to disregard any meaning you may be trying to convey.

Does anyone else experience this?
