Here's how Russians would try to use Pineapple pizza against Americans

Where did chunks of pineapple on Pizza Come from? Hawaii.

Where do Californians and people on the west coast go a lot to? Hawaii. (including myself by the way).

So, I tend to like almost everything about Hawaii including Canadian Ham and Pineapple pizzas which are also common in California (northern and Southern).

However, if you are east coast you might not like Pineapple on your pizza.

So, this is how petty things are used by Russian Trolls to try to divide Americans by their differences rather than how Americans join together on the big issues "like Russia trying to divide us in the first place!"

Or they might try to divide people in the U.S. by the way you actually eat pizza which means more people in the east coast would use a fork to eat pizza whereas on the west coast you never use a fork you ALWAYS use your fingers and hands to eat pizza. Then there is an east coast way of folding your pizza if you hold it a certain way which people don't do on the west coast when they hold their pieces of pizza.

So, you get how dividing people regionally by emphasizing differences rather than our unity contributes to "Divide and Conquer!" of how One country tries to conquer another like Russia is warring against American Democracy right now in revenge for the collapse of the Soviet Union around 1990 which Putin is still livid about and wants revenge on Europe, the U.S. and Saudi Arabia in specific for this collapse.
