Regarding Ms.Waters comments, we are being told by some that the Shampeachment trial of Trump is looking at comments he made "that go back years". So there is that.Perhaps some clarification is needed then, about which three are being referred to in the above quote.
I suspect we can remove Rep. Waters from the mix ... since her (quoted) comments were made back in 2018.
And I doubt that Vice-President Harris' comments qualify either ... since 1. I believe the (supposed) quote in the meme is not actually what she said ... but rather a paraphrase instead, and 2. she made her comments during an appearance with Stephen Colbert's show ... and generally those shows are taped for later rebroadcast ... so it seems rather doubtful that it was on "tv live" ...
I am quite curious though ... what exactly in "Protestors should not let up" is "hate filled" ?
Harris' comments were made after a summer of protests, malicious destruction, looting, and murders. The last three items I listed went with the territory with the protests. So telling protesters "not to let up" is signalling to them in a way that it's ok do the rest.
