Any third-party candidate trying to run for the president is either stupid or acting in bad faith. That's what the meme was pointing out. That's the reality of the situation in America until the work is done to fix the spoiler problem. If someone is competent and actually is acting in good faith, they don't run as a third party in US presidential elections. If their belief is we need stronger third parties, they do that by trying to change the electoral system at a more local level.
