I'm always amazed of the lefts capacity for justifying their evil using straw man arguments and blaming everyone else for the atrocities they are committing.
So let's see why this is bullshit.
-The way they are (medicinally) castrating children to change their gender identity/puberty. Future society will look back at this like we do lobotomy now.
There are two ways to look at lobotomy. A primitive surgery that was imposed on some people (savagery), a desperate measure some people resorted and voluntarily subjected themselves to when there seemed to be no alternative (usually in the past, but it still exists in some countries). First, gender identity is never imposed on someone, except if you deny their perceived identity. Second, puberty blockers when used properly are not castration and allow a person to delay any serious decision until they can better decide for themselves what is best for them.
-murder unborn children (Nazis would be proud of this, specially for non-aryan races)
Eugenism is imposed on others and practiced for irrational reasons, the right to have the choice to be able to have an abortion is not. Your "children" are not children yet and depending on the circumstances may never become, even without abortion.
-rioting in the streets in the name of "peaceful blm protests" with pre-delivered piles of bricks to boot!
BLM protests were not "in the name of peaceful ..." but were a statement that racism-based injustice is unacceptable. Some disorder is possible during massive protests and some provocateurs hoped to make more of it, events were exaggerated by those who want to maintain a status quo, etc.
-attempting and succeeding in propaganda and indoctrination in our school system (another thing nazis are very proud of, socialists as well)
Like forcing "prayer" in schools or institutionalizing anti-science uncertainty propaganda? If you mean the absence of that, it's for freedom, to allow people to practice their faith at home and in church. If you mean sex education or social awareness, it's just important and part of standard education in non-theocracies. As usual, misrepresentations of this are made to promote moral panics.
-the various institutions of "reverse-racism" against white people and others such as affirmative action, progressivism, reparations for history no one had part in, wokeism, etc.
Directly relevant to the above and evidence that you prefer bigotry and injustice instead of rights and equal opportunity. These are straw men, what you were denouncing above, remember?
-control of the mainstream media and social media with aggressive silencing of any opposing opinions. Nazi germany all the way up to modern communist states love this.
That doesn't happen, but private platforms often do for their own interests. It is also normal that some societies acknowledge that some type of propaganda can be dangerous to peace, safety or national security. As for actual freedom of press and mainstream media, the left is not the side advocating for censorship and control, the closure of public libraries, etc.
-using government police (FBI) and IRS to harass political opponents and anyone else who supports them.
False conspiracy theory. Evidence for your lawlessness and indoctrination into false narratives.
-politicizing and in some cases allowing to happen, mass shootings in the sole goal of disarming the people so they can more easily exact total control.
False conspiracy theory. Gun control is a good thing for safety, but the events you are describing is only evidence for that, none were "false flag operations". This narrative shows complete disregard for the family of actual victims.
-calling your political opposition "deplorable" similar to how the Nazis called other races "Untermenschen" to ease the acceptance of mass genocide of said peoples.
Where is your evidence that this doesn't happen from the right? Please point out instances of calls to promote crimes against humanty? I could fill a page of examples that come from far-right extremist platforms like Gab and from QAnon propaganda outlets.
-and most grave in my view, is frauding the presidential election to instill their own dictator over the United States in opposition to the people's vote, justifying it because "the current president is a nazi and he must be removed at any cost".
False conspiracy theory, the "big lie" disinformation promoted by Trump and allies to discredit democracy. False premise.
Those are all I can think of off the top of my head and I am sure there are more. But that should be enough to scare anyone who believes in the US constitution and values of a free society.
There are indeed reasons to be concerned when part of the population is completely lost in a false narrative.
