Yes, cause you don't deserve it. Information is at your finger tips, you can't comprehend them as you are not an expert of the domain, but you know how to contact some. While not always if one brings an extraordinary claim - like you did - or is uninformed their speech and sentiment is not on the same level to be regarded as others is. Especially since you do center your sentiment instead of that of affected.

But I have a brain and when I see someone disparage a country’s education system based off of a single percentage statistic I’m allowed to shit on it.

Show me where you did do "shit on it" when a person was "disparaging" a country which gets negative media bias in the US. Btw. you have no clue if they did do that based on a single statistic, that was only what was posted. No one will read a book as comment. You assume too much here. Also: The want to defend a country (or its reputation) instead of helping the people who could be affected is a problem, this means you are more a nationalist (and you seem to be US American, that means you are even centering your own country) than you care about people who are as example functionally illiterate.
