Depends on the state of mercury. Mercury in an inorganic state is survivable. It’d probably still mess up your organs. Organic mercury or mercury in its vapor form is a lot more dangerous, and can cross the blood brain barrier.

Tankie is a term used derogatory that essentially refers to people who are self proclaimed communists that support the CCP and other authoritarian governments that label themselves as communist. I’m decently sure the term is a reference to the Tiananmen Square.
The tankie triad is a reference to the 3 biggest instances for them: lemmy.ml, lemmygrad.ml, and hexbear.net
Now in all honesty I have only seen a handful of bad faith actors. Usually it’s because:
To me it’s hypocritical to be against the current authoritarian and fascist US, but also be supportive of the authoritarian CCP and Russia. It’s ok to recognize some actions that the CCP has done as an objectively good thing (like modernization of public transport), but they also deny the fact that the CCP has done atrocious acts and essentially bully the neighbors (aka the rest of Asia).
For reference I have no issues with the idea of socialism or even communism, but the CCP is far from those ideals.
