I believe in this case he means from beginning to end. Not all the time(Which is different from beginning to end. Because something can happen change happen again change and happen again and still have technically happened multiple times from beginning to end)
and I don't believe he means Everywhere.
Again. Throughout history doesn't mean all the time. Or the entire time. In which case a more appropriate word would've been Entirety, the whole of something. This doesn't mean the whole of history. Just multiple times throughout history. They have been treated that way, THROUGHOUT history.
But if you really wanna get technical he could still remake this meme and just add the words "Multiple Times" and then there would no possible argument. None at all. You are arguing over two words. You are really fighting Christianity over two words. Two Words that are unnecessary to use if you know the common uses and meanings of words in the English language. Anybody with any common knowledge of the English Language knows what he means.
I could argue that
1. By the definition of throughout, he is correct based on the "Beginning to end" not meaning "All the time" because if something happened multiple times from beginning to end it still happened from beginning to end.
2. if you won't accept that, then you must accept that you have made a stupid, useless argument that will gain you absolutely nothing, which is obvious by the fact that with simply TWO WORDS He could make this meme impossible to argue against. And honestly, I think I might remake this meme with those two words, just for clarification, since apparently, some people struggle with what people mean. This is like the "I ain't got no" argument. Yes it contradicts itself, but you should still know what it means, and you shouldn't expect a human person to have perfect Grammar, Perfect punctuation, Perfect spelling, or the ability to perfectly portray a thought. Especially not whenever it is a simple meme.
