Voting for Kamala Harris would literally have changed nothing, to be honest. Everything would have still sucked, and liberals would just have ignored it like they did for the past four years.
Kids would have still burned alive around the world, trans care would still have been banned nationwide by the GOP anyways, ICE funding would have creeped up gradually like it always does.
Trump accelerated the trends that already were there. He did not create any of the problems that are usually attributed to him by the democratic party. The far right cancer is deeper than Trump, it will exist without Trump, and you cannot ignore its spread during non GOP presidencies.
