Edit:
My most recent picture, however, is

Whataboutism doesn't really apply when pointing out a double standard. It's true that both places shouldn't do the bad thing, but it's more about the individual's reaction to that thing depending on who does it. The average US citizen will criticise the CCP for doing plenty of the same things their government currently does, or has done in the past, that they support.

Furthermore, it's important to note that when this kind of thing happens, people treat it as China's government's fault, but when Tesla cars explode, people don't consider that the US government's fault.

US as in USA as in United States of America, I believe

I think what they were specifying was the role GNU plays in that sentence. Personally I don't like calling one GNU/Linux and the other Linux, but the defining point of GNU is that it's uses only free open source software, and does not contain any non-free (as in speech, not beer) software.

Making all the transphobes come out of the woodwork to get banned with this one~ Appreciate everyone's unambiguous support <3

To my understanding:
Tankie refers generally to communists, but it depends on who's using it as to what it means. If a liberal uses it, they probably mean anyone left of Bernie Sanders. If an anarchist uses it, they probably mean communists, particularly any who "support" Stalin and/or Mao - their ire usually earned from "Victims of Communism" bullshit.

Essentially, leftists who use it are using it to decry people who are too uncritically supportive of current or past communist governments in their eyes. Liberals who use ir mostly just mean any serious lefty.

As if everyone with a cool idea can just whip up a company from scratch

"...we're talking over the radio." in the person on the left's speech bubble. Hope that helps.

I hardly remember what I was doing 5 seconds ago. Sure, that's more complicated than a number, and I think about my age rather frequently so remembering it is rather easy, but storing anything for a year and remembering it when I haven't thought about it for a while is difficult.

If I'm not mistaken, the Japanese Communist Party flag contains a cog.
