tuesday, LadySybil I was not at all saying that all of those who see toxicity in others are themselves toxic - what I was trying to say is that I personally know no one who in the heat of the moment could look at themselves and say "yeah, I am toxic". So, with that being said, the individual you feel is "toxic" may not have the slightest idea how their actions affect others. If that is the case, then it stands to reason that an individual (any individual) can be toxic and not realise it.
With much introspection and retrospection, I can say without a doubt that I was one damn toxic individual years ago, though.
I see it as more of an allergy than a blanket "poison". Just like "narcissistic" is thrown around as a £10 buzz word (I work in the mental health field and bona fide Narcissistic Personality Disorder has a very strict diagnostic profile - the people most of you are referring to are self absorbed) I see most people who are "toxic" are selectively so.
The person who to me is toxic may have friends and family who love them dearly. The part of them that I "react" to does not necessarily affect others in the same way.
I am hardly a perfect person - I am an introvert, tend to be "closed" and build walls that protect me and few are allowed behind them. To others, that might make me toxic - but I endeavour not to hurt others.
If that makes me toxic, then mea culpa.
Please note - I wrote a far better reply earlier, but the internet ate it. I am not saying that those who see toxicity in others are toxic - what I am trying to say is those who are (or seem) toxic are likely unaware.
