Is it even possible for someone to be a globe earther if they can clearly see the flat earth horizon?

Yes but the problem is that geocentrism is undermined by the lack of curvature.

What is wrong with  your eyesight; I see a curve.

If we are to take this by personal experience, then mine contradict what is seen in this man's video. When I was little we would sometimes go to Galveston and stay at a house my uncle would rent. I don't know the exact height, but adding tge sea-wall and a two to three story building means I would have been about the equivalent of five stories up. Anyway, from the top storey window you could see ships and even riggs out in the Gulf, but when you got down to the sand you couldn't see them anymore. It seems my experience conflicts with this video. Of course, being a decade ago you could just claim I maybe don't remember well. But that is that, make of it what you will.
   With the above in mind, a sphere does not have to be perfectly round. If you smoosh it just a bit, that slight oval effect could affect the seeming lack of curvature some people believe they see, like in that video. That is just something that seems possible in my mind.

That stupid video again.
.
It's all fake, and I've gone through it almost minute by minute already exposing the lies. The guy deliberately falsifies his pictures and you can even see what he's doing to make it look other than what it was when he shot the photos.
.
So transparent it's not funny.
.
He has his distances, elevations and observations all wrong. Pathetic.
.
This thread was started to go over another topic entirely and now it's turned into the same old nonsense.

Baptism of Desire syndrome all over again! That's what happens when you allow lunatics to get control of an internet forum.

This is incredible.
.

If you would have used binoculars and a zoom camera just a few feet above ground level, you still would have been able to see the ships .

.
Flat-earthers are so myopic it's predictable.  
.
He just told you that he could see the ships without binoculars from the top story window at 5 stories up, so why do you think that when he goes down to the sand -- which is CLOSER to the ships! -- that he would need binoculars to see them?

Baptism of Desire syndrome all over again!

Globalism and geocentrism do not go together. It is a physical impossibility. You cannot simply reverse the position of the sun and earth and retain all the rest of heliocentrism. It is physically impossibly.
.
Regardless, your helio/hybrid version of geocentrism is easily disproved with the mere use of one's five senses.

There is no curvature to be seen anywhere, whatsoever.
