I disagree. Many of their grievances have been mislabeled as racism, sexism, etc., as a way to dismiss their point of view and ridicule, rather than debate the merits.The "angst" and "grievances" you are referring to, was really, racism, anti-immigrant racism, animosity towards cultural change, and fear of white dominance ending. None of these are actual legitimate grievances. These sentiments did not come out of the Obama era either, or because of it, they always existed. The 2008 recession, amplified it with the creation of the Tea Party, widespread hatred for corporations and media, coinciding with a black man coming to power.
Back then it was the white replacement theory, white flight, "terrorism", anti-LGBTQ attitudes because of religion, gun control etc., Today it is against "woke".
Meanwhile, "woke" is nothing more than marginalized folks, such as POCs, LGBTQ+, Women - people no longer willing to put up and shut up, voicing their opinions, engaging in activism and demanding change. And they have been hugely successful.
So between the two groups - the progressives and MAGA, only MAGA qualifies as a populist irrational cult, based purely on hatred. And sure enough, the ones who act as MAGA custodians and leaders, are all frauds, con men, assholes, creeps, low IQ morons with a twitter account, etc.,
Wanting to preserve American culture and Christian values is not racism. You may disagree with the stance that preserving American culture and Christian values is important (which is a fair argument to make), but accusing that stance of being racism is lazy.
Wanting to limit immigration to controlled, legal means is not racism. Unchecked illegal immigration is causing problems in cities all across America, with even Democrat mayors now speaking up about it. Whatever immigrants that are taken into a country should be able to be properly accommodated and assimilated into normal daily life of the host country, including employment. There should be a means to quickly make this transition with only temporary government assistance.
Being pro-life is not sexism. Even though I'm pro-choice myself, I understand that the abortion debate is tricky, with valid arguments on both sides. On one hand, you're actively preventing a life that otherwise would have come into being without the intervention. On the other, an unwanted pregnancy has a huge impact on the life of the parents, particularly the mother, and may pose a health risk to her as well.
Being against hormone therapy and more aggressive interventions (such a surgeries) for minors is a valid position to take, and shouldn't be labeled as transphobic. Research into the effects of these actions is highly politicized and therefore difficult to properly assess. But even research that suggests hormone therapy is reversible usually notes that it's not fully reversible, but merely that puberty will start up upon its absence. What limited research there is has shown that growth is impacted in individuals who delay puberty in this way. And we have very little research into what other impacts may have occurred when a human body is not allowed to go through puberty in a regular timeline.
I'm sorry, but both MAGA and progressives are largely irrational cults that spew hatred. Neither are particularly interested in discovering truth. The confirmation bias of both groups is extreme, and they won't listen to contrary arguments. They label, and skew, and deflect...whatever is necessary to project their own ideology. It's a sad state. The only saving grace is that the loudest, most extreme voices of each are a minority.
