There is the "just asking questions" rhetorical trick, where someone asks something that sounds a lot like an outlandish assertion, and then defends themselves by suggesting they don't actually believe this thing — they're just asking if maybe it's worth considering.
There is also the “firehose” trick, which essentially amounts to saying so many untrue things in such a short period of time that refuting them all is nearly impossible.
Much more difficult, for all of us, is to engage the best ideas you disagree with, think about them honestly, and explain clearly why you don't agree. And even more difficult is to debate honestly, discover that the other person has made stronger arguments, adapt your position and grow.
Omitting key information in arguments, or omitting counter-evidence to central claims, is just one bad argument style that is common in politics.
The curse of whataboutism is that we can often do it forever. If you want to talk about White House nepotism, it'd take weeks (or years) to properly adjudicate all the instances in American history, and it would get us nowhere but to excuse the behavior of our own team. That is, of course, typically how this tactic is employed.
Bothsidesism: Naturally, this is what I get accused of the most. I'd describe bothsidesism as a cousin of whataboutism. Wikipedia defines it as "a media bias in which journalists present an issue as being more balanced between opposing viewpoints than the evidence supports." An example might be presenting a debate about human-caused climate change and giving equal air time to two sides: Humans are causing climate change vs. humans aren't causing climate change.Given that the scientific consensus on climate change is robust, arranging an argument this way would lend credence to the idea that scientists (or people in general) are evenly divided on the issue, even though they aren't.
A straw man argument is when you build an argument that looks like, but is different than, the one the other person is making — like a straw man of their argument. You then easily defeat that argument, because it’s a weaker version of the actual argument.For instance, in a debate on immigration, I recently made the argument that we should pair more agents at the border with more legal opportunities to immigrate here, a pretty standard moderate position on immigration. I was arguing with someone who was on the very left side of the immigration debate, and they responded by saying something along the lines of, "The last thing we need is more border agents shooting migrants on the border."Of course, my argument isn't for border agents to shoot migrants trying to cross into the U.S., which is a reprehensible idea that I abhor. This is a straw man argument: Distorting an opposing argument to make it weaker and thus easier to defeat.
"The straw man is a terrible argument nobody really holds, which was only invented so your side had something easy to defeat. The weak man is a terrible argument that only a few unrepresentative people hold, which was only brought to prominence so your side had something easy to defeat."
This is classic moving of the goalposts. We went from “there weren't classified documents” to “they were classified but not that serious” to “they may have been classified but the raid was unjust unless there were nuclear secrets” to "okay, but he wasn’t selling the nuclear secrets to Russia."
The "prove a negative" argument is when someone insists that you prove to them something didn't happen or isn't true, which implies that they have evidence something did happen or is true — but they don’t actually present that evidence.For instance, if I asked you to prove that aliens don't exist, you might have a hard time doing it. Sure, you could argue that we don't have an alien body locked up in some government facility (or do we?), but you’d have a hard time listing the contents of every government facility. And if you could somehow do that, you haven’t proved that aliens don't exist at all, or even that they've never been to Earth. But the burden of proof isn't on you to show me that aliens don't exist, it's for me to show you evidence that they do.This was, in my experience, one of the most frustrating things about some of the early claims that the 2020 election was stolen. A lot of people were alleging that Dominion Voting Systems was flipping votes from Trump to Biden, and then insisting that someone must prove this didn't happen. But the burden of proof was not to show that it didn't happen (proving a negative), it was to show that it did happen. Which nobody ever did.
