Republicans can fall into hysteria and moralistic pontificating (Freedom Fries 
) too but never as much as the Democrats whose entire platform is existential fear-based rhetoric.
I'd argue that the majority of the Republican platform (aside from tax cuts for the rich/big corps) is riling up their constituents about existential "threats":
TURRISM!
MUSLIM PRESIDENT!
ILLEGAL IMMIGRANTS!
ANTIFA!
GAYS MARRYING!
TRANS BATHROOMS!
PEOPLE SPEAKING OTHER LANGUAGES IN PUBLIC!
WHITE DEMOGRAPHIC DECLINE!
WESTERN CULTURAL DECLINE!
SHARIAH LAW!
BENGHAZI!
STOLEN ELECTIONS!
CRITICAL RACE THEORY!
And moral grandstanding? The anti-abortion, pro-evangelical, "Christian nation" party has that on lockdown. I'd rather 100 SJWs tell me I'm a racist and a colonialist oppressor for failing to use the term Latinx than a single bible thumpin' evangelical giving me a sermon on why I'm going to hell for being a nonbeliever.
And while being chicken little doesn't help the problems, at least the Dems are worried about things that have actually caused death and destruction - covid deaths and extreme weather conditions due to climate change.
I will be first to concede that yeah, conservatives do raise the alarm a lot but I think a big liberal problem is discounting these issues. Take the refugee situation. It is a complex situation but the way the left tells it anyone that has concerns over safety is a bigot even if they admit empathy towards their plight. The left undercuts how many of the issues you listed change or alter society and then guilt trip if you don't support their way.
MARY AND JOSEPH WERE REFUGEES YOU BIGOT!!
AMERICA LIMITED JEWISH REFUGEES DURING WWII. YOU BY NOT SUPPORTING MORE REFUGEES PROVE TO BE A NAZI BY ASSOCIATION.
You could say both sides don't have empathy towards the others' concerns and that's a problem.
The problem is that liberals tend to discount these issues and their complexities. Take illegal immigration. A lot of Latinos don't support it (or Latinx now that I think about it) yet it's curated as a topic only racists don't support. Why wouldn't illegal immigration and borders be considered a serious issue? You list the issue of the lefts concerns being one of death and destruction just days after a man from the UK flew to Texas and held a synogogue hostage. So in what way aren't borders a legitimate safety concern? A massive liberal failure is taking complex issues and labeling them in binary ways.
Take critical race theory. History should absolutely teach the realities of America's past. The problem is that CRT teaches that race is a part of every single interaction and typifies one's lice experience solely through a racial lens. At that point it stops being history. And it's being taught to grade school students? We should be more honest in what we teach our children of the Great American Myth but teaching our kids that their life will be typified by their race as an oppressed/oppressor dynamic isn't good for the children nor American society. This is a valid concern yet the liberals, in their liberalism, naively shoo away any criticism just like they shoo away any criticism of drag queens reading to kids in libraries with sex convictions.
A fatal flaw of liberalism is it has no idea how too much is too much. There's always more, more, more and don't consider how their choices alter society in some naive pursuit of truth and justice. So they call people that don't support Latinx bigots even though Latinos would rather be called be a spick than Latinx and naively support CRT in some blind wokeness when many black people openly resent it.
The issue is one of empathy. Liberals don't empathize with conservative issues and conservatives don't empathize with liberal issues. But overwhelming in my experience, conservatives are more likely to understand the complexities of an issue than liberals who tend to be more binary. Covid deaths was an issue when Trump was in office and there was no vaccine but now that there is a vaccine and there's more Covid deaths under Biden than Trump suddenly liberals love making fun of those that die because it's mostly the unvaccinated. Then, in their want to be more safe, they take shit too far.
The site Benji posted the other day tackles this in an article. Liberals love to not know what people actually think in some naive pursuit that it's only a concern of Fox News and hardline conservatives again proving their inability to communicate or understand the complexity of issues. Even if you support a liberal cause, like Covid safety, it becomes an issue of HOW. How to reduce deaths? Vaccine is a great way. But HOW do you get more people to get the vaccine? The left thinks a mandate is how things should be done and people should be forced to get it. But if you disagree with that then you're obviously an anti-vaxxer. Why? Because limitations of HOW. Liberals think only their solutions are the solutions worth doing or talking about and unwilling to engage in discussions. Why limitations in how things are approached? Because to the left there's only one solution. Again. Binary. If you're not with us you're against us. You can take the issue of How on every single issue and liberals don't fucking get it because in their bubbles they have concluded only they have the answers to society.
