I don't flat content I don't like. I flag content for various reasons including but not limited to:

1. They use a post as their soapbox for an irrelevant topic, such as religion.
2. Makes unsupported claims that the person will not provide evidence for
3. When someone's claims have been proven wrong and they will not concede, but they continue the discussion trying to change the topic
4. Continued logical fallacies.

I won't address the God issue. It's irrelevant and unsupported that they 'hate' god so that they invent things. That is called an unsupported claim. Please refrain since it's irrelevant and just your opinion.

Again, your allegation about lighthouses doesn't even make any logical sense. I have zero idea why you would think a lighthouse would not make sense on a globe. It sounds like something you heard on a video that you are just repeating.

And the experiment above, that is the topic of the posts, was done in ancient times. It takes no complex math or fancy equipment, and provided strong evidence the earth is a sphere with a far away sun, as do many phenomenon we see every day that you could do yourself if you wish.

So, really, you made three points,one of which was an unsupported opinion irrelevant to the conversation. And two that made no sense and were not supported by any facts or logic.
