> If your assertion of people own blenders were true, there would be no whipped cream shortage [...]

Let's take it from here. My assertion was that people own blenders for more than just whipped cream. In other words, I claim that people use blenders also for other things.

Given the article's claim that there is "whipped cream shortage" and how implication ("if..then..") works, you basically say that my assertion is invalid, meaning that people only use blenders for whipped cream.

Now go back and rethink what your stance is and how to convey it, because you surely didn't mean that.
