Nope, no selective memory here. I know what I eat. In the last two years, I've had red meat three times, twice at Thanksgiving, and last March, I had an In and Out Double Double when I was in Ventura for work. In the past 18 years, I've had red meat about a dozen times, and pork once (in a migrant farmworker's camp--- I felt guilty refusing the sweet abuela who prepared it). I was all Veg all the time for about 10 years, but missed seafood too much, so I have it a few times a week, and have poultry rarely.
I'm in great health, and feel good. It works for me, more meat works for other people, no problemo.
Like Een, in that I don't give much thought about what anybody else eats. IMO, neither should anybody else.
