There is nothing wrong with questioning concepts like perspective...Questioning such concepts is the very right and very intelligent thing to do.
It's not the questioning that is the problem, ask all the questions you want. The problem is the unreasonable rejection of answers.
FE Question: Why do you RE people think the Earth is round, can't you see it is flat? Look around you!!
RE Answer: Well, photos from space, for example.
FE Response: Nope, those are fake. In fact, ALL space flight EVER has been fake.
RE Answer: All right, I suppose I can't 'prove' spaceflight to you. Eclipses aren't fake though, and they demonstrate the Moon going around the Earth.
FE Response: No, the Moon goes around the north pole, sometimes passing in front of the sun.
RE Answer: If that were true, the phases of the moon would turn sideways sometimes!
FE Response: No they wouldn't
RE Answer: Of course they would, how can you even.....whatever, how about Lunar eclipse, when the Earth is between Sun and Moon?
FE Response: Shadow Object.
RE Answer: Shadow WHAT?!? Never mind, star trails prove the Earth rotates among the stars.
FE Response: Dome.
RE Answer: What?
FE Response: The stars. They're on a dome, and that's what rotates, not the Earth.
RE Answer: How....why are the stars in the southern hemisphere going the other direction then?
FE Response: Gears.
RE Answer: Gears?
FE Response: Yes, northern and southern celestial systems.
RE Answer: So which is it then: a dome, or two systems?
FE Response: I don't have to answer your questions.
RE Answer: Seriously? OK then, why do ships disappear over the horizon hull-first?
FE Response: They don't.
RE Answer: What do you mean, "They don't"?!? Of course they do, I've seen it happen!!
FE Response: No, you THINK you've seen it. Get a better telescope, you'll see the whole ship again.
RE Answer: Here's a photo taken with a pretty extreme telephoto lens, proving you wrong.
FE Response: I don't believe photos (except the ones I put up, of course)
RE Answer: Are you kidding me? All right, all right: shadows of the sun form different angles at different locations.
FE Response: Sure they do. Because the sun is 3000 miles away.
RE Answer: No, it's because the observers are on a curved surface looking at a far away sun.
FE Response: No they aren't.
RE Answer: But if you take observations at different spots, you can calculate very different solar elevations if you do the math FE style, while getting the same number doing it RE style.
FE Response: That's because you Round Earth people think PI = 3.14159
RE Answer: Of course we do, why wouldn't you?
FE Response: Because Pi = 4
