Seriously what the fuck is this? Googling this specifically because someone in my fam shared a boycott list including Shein and Temu and I thought hang on, what are they doing to fund the genocide in Israel, and saw that it was a boycott for the very real Uyghur genocide
Absolutely, they won't allow any criticism of the democrats without shifting the conversation to Trump. Ofc there are times when bringing up another topic for context is relevant to the conversation, and times where it's not, which is why shouting "Whataboutism!" at everything is dumb and just an attempt to exert control over what topics are allowed to be discussed.
If the question you're trying to answer is, "Should I vote for Biden or for Trump?" then bringing up Trump's shit in response to criticism of Biden is fair. The problem is that liberals are incapable of having a political conversation that doesn't center that question, to the exclusion of all other options and all facts and analysis that aren't relevant to that question. The fact that the CDC betrayed public trust and caused countless preventable deaths doesn't fit neatly into that question, so that fact is not to be brought up in conversation, and if it is, then it must be because the person bringing it up is trying to make an argument for voting for Trump, because that is the limit to liberals' perception of reality.
