I agree. The problem is how some people kept looking for loopholes that allowed them to say it.
“Can I say it if I’m quoting Mark Twain? Can I say it if I’m quoting Quentin Tarantino? Can I say it if I’m quoting the lyrics to a rap song? Can I say it if I’m being ironic? Can I can it if I’m wearing a disapproving look? Can I say it if I pronounce it slightly differently? Can I say a word that sounds like it?”
If you tell these people they can’t say it a thousand times a day, their response will be “So it’s okay to say it nine hundred times a day?”
Eventually you just have to tell these people that they can never say it under any circumstances. It’s the only way you can stop them.
