I'm no biologist, but even assuming all of that blog post's sources are reliable - it is still cherry-picking findings:
* Not counting livestock contribution to GHG, but rather an estimate of how much removing it would reduce GHG (which is room for a lot of speculation that is very hard to support).
* Preferring a figure taken from a single paper by two individual researchers over the United Nations' official FAO statistic, which is 14.5% of emissions due to livestock lifecycle.
* Focusing on how forestation is challenging, while the source acknowledge that the de-forestation is very damaging.
* Ignoring the huge amounts of land necessary for growing livestock (Example: ~55 times the area for peas for same amount of protein [1])
* Ignoring the question of the distribution of meat consumption among people in the world today, and the feasibility of a meat-rich diet for everyone.
I'm sure there's more, but this is enough not to be very receptive to the claim of misguidedness.
PS - Due disclosure: I eat poultry and occasionally other meat. But I am still worried about the environmental impact of its production, with the foremost aspect being de-forestation.
