That user may not be trying to dunk, but I am. As that user said, Republicans at the RNC gleefully held signs at the RNC saying "mass deportations now" and everyone heard Trump saying Haitian immigrants were eating cats and dogs. There was no "information environment" that hid this information from voters. They heard Trump's explicit promises of violent xenophobia loud and clear. They knew. We all knew.
We have got to stop treating voters like children who can't possibly be held accountable for their actions. There's a fucking legal age requirement for voting for a reason--because it's assumed that by the age of 18, people are old enough to understand the world around them and that there's a cause/effect with their actions. These MAGA fucks weren't some sheltered, lost lambs who had no idea what they were doing. Every Trump voter did vote to deport moms, it's just that some never thought they would face consequences for their actions, so now they're trying to rewrite history and deflect blame. That's all it is.
Democratic politicians may not be able to treat them with the contempt they deserve without facing electoral backlash, but the rest of us are under no obligation to entertain these people's lies. People refusing to hold MAGA accountable for supporting the most gleefully, proudly awful person alive is a big reason why we're back in this fucking hell 8 years later. These people should have been shamed from polite society way back in 2016. Fuck them. The guilt should keep them up at night for the rest of their lives.
