Do you not consider this a meme? If I may ask, why not?

Frankly, I have trouble defining what a 'meme' really is. Traditionally, a meme is an idea of some sort that spreads through a culture. A more modern definition would be:

An amusing or interesting item (such as a captioned picture or video) or genre of items that is spread widely online especially through social media

So personally I would say this post a meme and thus belongs here. However, I don't know if Webster's definition is really what posters here, and more importantly the mods here, would use.

Does spitting fire as truth have a right to our memes?

Good point. Technically it is, it's just not funny.

Yes and yes. Any further questions?

The fullfilment of prophecy to bring about the end times according to their doomsday cult.

Yeah, "does Israel have a right to exist?" is a nonsense question. What's the difference between a state with that right and one that doesn't? Is a state that has a "right to exist" therefore somehow beyond reproach? I think it's a rhetorical tool that is meant to confuse people, because any clear eyed understanding of reality leaves Israel looking obviously terrible.
