I don't. I just take issue with your grouping.
For what it's worth I grew up in a country that would be considered western where grass-fed is the default.
Where exactly did you grow up? Without that detail “grass fed” is as meaningful as “cow goes mooooo”
For the record, I also think calling grass-fed beef gamey, metallic, and saying it's unlikely to be popular (like the top-level reply did) is an overstatement. The most prominent thing is the different coloured fat. The taste isn't hugely different, probably because our grass-finished beef still gets enough feed.
I don't understand why you would write something like that in response to a pretty normal discussion. The whole point was that I don't care what feed the beef was finished on.
