No you sad fucking tool, there is a distinction between an unofficial leaderless movement protesting injustice and a corrupt and pathetic leader packing people together on govt. property for a self-serving political event. That is what the part about taking the presidency seriously is about; the president is responsible for his actions and his leadership. That he used the event to spout bunch of crazy nonsense and lies, embarrassing himself even more than usual, also shows how much he's debased the presidency. See, because you're a cretin with no character, you can't understand how this is a total failure of leadership; you're just fixating on your usual asinine culture war bullshit like a dumb child.
If Trump had used the WH for an event where he livestreamed a speech of him, standing alone, ranting about QAnon conspiracy theories and asking people to guy his penis-enlargement supplements, that would be unobjectionable from a coronavirus-transmission perspective; it would, however, still be a fucked-up failure of presidential leadership—and Biden would still be able to ask when Trump would take the presidency seriously. That being said, from a pandemic perspective, there's probably a difference between packing people closely together to sing loudly without wearing masks, and mask-wearing people moving around with a lot of space between them. Even if that had not been the case, from a moral perspective, there's a difference between taking risks in order to fight severe injustice, and inciting others to take greater risks in order to participate in a self-serving—and incredibly fucking embarrassing—political spectacle.
The really pathetic thing is that you don't even know what you're trying to argue, here; you're just pulling increasingly stupid attempts at whataboutism out of your ass, hoping something will stick—and only succeeding in showing more of your ass with every attempt.
