Uh... no, it can't. You could just say, "Puking into a toilet," instead of, "Speaking Chinese." That was incredibly insulting to them (even despite their society facing all sorts of issues). What if I said that pooping off the edge of a skyscraper could be called, "Speaking American?"

They're equally preposterous. Idk where your relative got that phrase from but it's certainly not well-known, nor should it be well-received.

Here's the thing - critical race theory states that you can't be racist towards the French. You can be prejudiced against them, but not racist.

You might be seeing why idpol dogshit like this is treated so harshly.
