It comes down to how American conservatives are extremely hostile to any kind of change whatsoever. In more extreme cases, like MAGA, QAnon, TeaParty, etc. that hostility towards change can lead to fear, which can lead to things like violence, terrorism, hate groups, etc. In short, they are called conservatives because they wish above all else to “conserve” the status quo (as they see it), that often being racism, sexism, slavery, xenophobia, hate groups, misogyny, white supremacy, Christian fascism, etc.
