FL, I think all you can do sometimes is ignore someone.
I 'love' the tough-guy stuff people try to pull. There's nothing they can say to me that I haven't said to myself, and after decade of denying reality like that I was trashed, physically, cognitively and emotionally. I did it and had to get smarter than cute 'tough guy' slogans.
And, I just remembered -- there's a book called "Brightsided" that criticizes the cultural explosion of -- sort of -- "inverse positive-thinking." That is, that rather than bad events causing bad thoughts, that bad thoughts cause bad events. The author got cancer and even found that belief in cancer support groups (that if you have no negative thoughts then you won't die -- so if you do die, then it's your fault).
