It's not just the President. Any number of people, it seems, are coming up with long diatribes backed by the flimsiest of "facts," and in this world of instant news, the diatribes go viral in minutes. The worst offenders, it appears, are generally labeled "Copy and paste, don't share," presumably so no clue of the dubious origin remains.
So, no, security for Melania and Barron will cost a lot, but not $184 million a year. And no, the budget doesn't directly eliminate Meals on Wheels, though it does cut block grants that may occasionally be used by states to fund programs like Meals on Wheels.
The point is that it's exhausting and honestly impossible to keep up. But everyone who copies and pastes these items reduces by a smidgen any credibility that our side has in facing up to the genuine, reprehensible actions going on daily. We have to call bullshit on the bullshit as we can; stop imagining that just because a trusted friend posted it, it's real; and fight the power, not each other. Plus do our own research whenever possible. It's hard. If we could run the country just by retweeting bullshit, we'd have no problem with the president we've got.
