I didn't mean it to be gleeful at all. If I had a typo, I'd want to know too. I used a smile emoticon to try to convey friendliness and I'm sorry it didn't land that way. I would rather have DMed you about it, but didn't see any way to do that on Medium. Now that the message has gotten to you, I'm happy to remove that part from the original comment!
The quote you share in this reply is 100% accurate. But in your article, you don't say "in the non-annexed portions of the West Bank" - you say "in Israel." This is the key distinction that makes your sentence false. If you just changed the sentence to "Palestinians in territories occupied by Israel can't vote in Israeli elections," then it would be true. Best wishes.
