YABU. I’m not going to start stressing about how much chicken I consume when there are already a million other things to worry about. And it is unreasonable to try to change other people’s eating habits.
FWIW, I don’t eat meat every day - because I can’t afford it. I also never fly anywhere (can’t afford it), only drive when necessary (can’t afford to waste petrol), only buy clothes when old ones wear out (can’t afford frivolous spending). I could go on and on about how environmentally friendly I am (right down to using bars of soap rather than bottles of shower gel). But it’s not because I’m overly concerned about the planet, it’s because (like millions of others) my life is ALREADY low consumption because I’m skint!
I honestly think that the only people who should be allowed to try to guilt others are those who are already in the bottom 25% of the country for environmental impact. Everyone else can keep their moralising to themselves.
