I pointed it out because I clearly took issue with your lazyness. OP made a specific claim of evidence. Instead of refuting it directly, you linked to a (biased, uninformed and weak-manning) dismissal of the whole hypothesis which didn't even address this specific claim of evidence even in passing.
That helps no-one.
It did not help the flat-earthers who only will see your comment as a confirmation of their own bias ("those globalists are so brainwashed that they are unable to grasp the simplest concepts of trigonometry"), it does not help a globalist who will not take a second to think about the argument ("flatearth BS lolölol"), and it certainly doesn't help someone who is still on the fence and trying to form an educated opinion ("OP made a good point if true, and if telos' rebuttal is the strongest globalists can come up with, there must be something to flatearthism").
It was all fine until I pointed out how weak and uninformed your argument was - then you lashed out with insults and strawman arguments, further hurting your case. So if your intention was to combat misinformation, you failed miserably; if it wasn't, and if you don't have the time or means to, then it would have been better you had remained silent and you were mistaken for a philosopher than speaking and remove all doubt. Then truly, this content was not addressed at you at all.
That is all I was trying to say. I am a "conspiracy theorist", which means I doubt "conventional wisdom" a priori, but also a "critical thinker" and a "skeptic", which means I don't accept as fact everything I'd like to hear. In short: I take no sides. I want the arguments for either view to be sound and clean so I can, maybe, one day, form an educated opinion on the matter. Teaching others how to lead such discussions is my mission.
I am quite convinced of the rotundity of the earth myself, by extrapolating from the shape of the moon and planets, but as you can see from my blog, I have almost 10 years of 9/11 debate under my belt, and there are patterns of "debunking" that are simply detrimental to the cause of truth-finding, by blatantly proving to be debunker's attempts at convincing themselves of their own superiority, not to shed light onto a problem of science.
Bluntly: facts were presented, nobody cares for your opinion!
I mean, look at it. It's essentially pure math. The rules should be clear. Even if OP were simply "stupid" for claiming 3x3 be 10, you don't call him/her stupid for not being as wise and intelligent as yourself, you say "look, this is how to solve the riddle", for all the world to verify or, if necessary, correct or discuss.
If you can't do that, that's okay. But please, please don't insult independent thinkers with links to rationalwiki or snopes or something like that. There is a huge probability those were the first sites they checked when their world view first went helter-skelter when confronted with a piece of evidence such as this one.
Again: I meant no offense, I only sought to make clear you are hurting your, and by extension, my case and that of all skeptics. And also, I would like to try and do my part to help this network in particular not to imitate the "debate" culture known from the rest of the web.
Let us try to be excellent to each other. That is all.
