The irritating thing about Poison Ivy as a character is that:
1. Poison Ivy isn’t a villain because she kills billionaires, she’s a
villain because she sincerely, unironically believes all that Perhaps
Humanity Is The Real Virus claptrap, and she’s prepared to make that
everybody’s problem. If she were a climate change activist, she’d be the
kind who thinks the oil company CEO and the minimum-wage janitor who
cleans the executive toilet that CEO shits in are equally culpable;
her attitude embodies a very real failure in mainstream environmental activism to properly distinguish between individual and collective responsibility.
2. This is almost certainly completely accidental, and 90% of the people writing Poison Ivy in an official capacity probably aren’t thinking about it any more deeply than Scary Eco-Terrorist Woman Bad.
