As Twitchy reported yesterday, presidential candidate Hillary Clinton announced that she’d be appearing at a church in Florissant, Mo., this afternoon, leading some to wonder which of her many fake accents she’d adopt for the mostly black crowd. Little did we know, though, that Clinton would commit what some consider the most offensive faux pas imaginable just minutes into her address: she proclaimed that “all lives matter.”

As long ago as last December, Cornell University’s police chief ended up apologizing in an email to the campus for using the phrase, which she wasn’t aware was considered “disrespectful pushback against #BlackLivesMatter on many Internet forums.”

Clinton apparently didn’t get the memo either, sharing an anecdote in which her mother told a young Hillary that “all lives matter.”

Regardless of context, those three words should not appear together in sequence in America in 2015.
