It wasn’t meaningless, and I went out of my way to make clear the sample size wasn’t statistically significant.
The point was that the parent comment implied there was no reason to start eating meat again after making a moral choice not to. My anecdote shows that some people do anyway, therefore there must be a reason.
That in my experience they tended to be the people who relied on meat substitutes was part presented as an observation of interest, not as hard evidence of universal truth.
